that dabbles into quantum mechanics. to put it simple, certain objects absorbs certain colors or "wavelength" due to its atomic makeup. absorption is simply a property of light and color is the evidence for absorption. each color has different wavelengths which certain objects can only interact with or absorb, the colors that arent absorb is reflected, and transmitted.
Well that is understood, the question is: what makes objects reflect specific color? Everybody is explaining how we see colors but no one is telling what makes objects absorb all colors and reflect only one, what does it depend on.
To answer your question, we would first need to understand that the appearance of the color of an object depends on the amount of light hitting that object. For example, if we have a red scarf and put it in a dark room, you would not see that it is a "red" scarf, you would actually see this as a very dark, close to black, color, depending on the lack of light. However, if we add white light, the color of the scarf stands out to our eyes. White light contains all the colors in the visible spectrum. The color of an object such as the scarf is a result of the interaction of white light and with the atoms of the material. These atoms selectively absorb, transmit, or reflect the light hitting the surface at very specific frequencies. Selective absorption is the nature of an object to absorb some frequencies of light more than others. In the example of the scarf, every color that white light contains would be either transmitted (if the material was transparent) or absorbed, while the red color would be reflected. Why is this? Well, any particular color of light is absorbed when the frequency of that light-wave matches the resonant frequency of an object. Resonant frequency would be when one object (white light waves) causes the second object (red scarf atoms) to vibrate at the same frequency. When the frequency of that particular color of red reaches the scarf, they are reflected, so we see a red scarf as opposed to other colors. For more information, please email us at techsup@edmundoptics.com.
Edmund Scientific I will definitely contact you about it, another channel also replied with a link to a resource that I couldn't access but the book was also talking about the development of resonance theories. However I am so thankful for your kind reply and your will to explain further and make everything logical and clear.
Edmund Scientific so when you say resonant frequency you mean that specific frequency of the photons of the white light is met, matched or amplified by an other wave, right? Because resonance occurs with waves, what is the source of the wave that causes this resonance? Is it the electrons of the molecule? Is that what specify the reflected or amplified wave that our eyes distinguish as a color? If this is true then we (our eyes) should get a different color (frequency) if there is a change in the characteristics of these electrons which must change the frequency that makes the resonance and reflection of a specific color. There must have been a research or at least an experiment to prove it if what I'm thinking is right.
Edmund Scientific Just how an object says:"Oh, OK I'll vibrate with resonant frequency" ? It's gotta be something with the object itself, I know that white ight contains all of the frequencies of the other colors, but how a color is reflected must depend on the object itself.
ok so what happens to the absorbed wavelengths on the atomic level then? will the atoms absorb and release them in the form of heat or other longer invisible wavelengths? and what happens on the same level with reflection?
Although white light contains all colours any three colours of light can be combined to make white. Prisms can both combine and separate colours from and into white as well.
2:27 Excuse my ignorance, Isn't the red gummy bear red because it reflects red wavelengths? In that case, isn't it suppose to reflect (not absorb) red light?
Hi, thank you for the insightful video. But what baffles me the most is: why do we say light is a wave? Okay... I know it is a vast topic but my question is very simple: Wave is defined as a disturbance, so light is a disturbance. And disturbance means something is disturbed. Like in sound wave, air molecules are disturbed. But what is disturbed in light wave? People say it's a transverse wave which means whatever is being disturbed, is disturbed perpendicular to the motion of the wave. What exactly is that? And how do I visualize wavelength? I mean all these terms, wavelength, amplitude, frequency, time period sound so deceptive. Like amplitude can be visualized as the maximum displacement of the particles ( in case of sound wave ) and wavelength?!!! They say wavelength is the distance between two crests!!! But crest is just part of a mathematical graph of wave! Amplitude is real, wavelength is not. Please help my troubled mind out. Thanks!!!
Light consists of electromagnetic waves. They consist of oscillating electromagnetic fields, where the magnetic field oscillates perpendicular to the electrical field. Wavelength is more real than just a distance on a graph, since the crests have a real physical existence. In the case of electromagnetic waves, it the crests would be the points of maximum electric field strength in a particular direction.
It will come out blue. And now that may make you think that she was wrong when she said that the sheets absorbs everything except the color of the sheet and you're right. It absorbs the complementary color.
but WHY? What makes two different gummy bears absorb or reflect different colours? What is it about dyes that cause this? Are the two bears molecularily different?
So an unripe green tomato absorbs all colors and reflects green, and once it ripens its molecular structure changes to then absorb all colors and reflect just red?
I tried it. I had to spend $9000 for a color light source powerful enough. It didn't color the red gummybear the same color as the green laser but it did open up a portal to the afterlife for 5 seconds and i saw my grandmother fart a big one and the portal closed.
Absorbed light mostly goes into heating the object, and objects readily exchange heat with their environment. All else being equal, a dark object exposed to light will be warmer than a white object. Out in the sun, a blacktop parking lot will get warmer than a white cement sidewalk.
I think so. The dark color/ pigments of the shorter wavelength violet, dark blue, light blue absorb more energy than the longer wavelengths of yellow, orange and red. We know a black, violet or dark blue shirt exposed to the sunlight of a winter day is warmer against the skin than a white, rose or yellow shirt. I live in Tucson and for shirts of the same material, definitely a white, yellow, or light blue shirt is cooler against the skin than black, violet or dark blue. Just sitting in the sun, the hoods of the same material of a white car in summer is cooler to the touch than a black hood. Blue stars are the hottest and red stars are the coolest.
Nice video. It's not really though that a lime only reflects the green wavelengths. The light that it reflects looks green. However, this light includes light at all visible wavelengths in the spectrum (but each to varying extents). The reason that I don'y like the misconception that the lime only reflects the green wavelengths is that is wrongly suggests that light is coloured.
I have a doubt- what if we pass white light through 2 filter only? According to the explanation, no light should pass.. because 1 filter(green) absorb all frequency of light except green frequency ..than it pass to 2nd filter(red) which will absorb green frequency.. therefore no light will pass
so there was 2 gummy bears that are the same: they were wade from one ingredient the same way, but why did one of the gummy bears observe green and every other color except red and the other observed red and every other color except green
Doesn't texture in living things such as butterfly wings also create color? Obviously this still goes along with what you're saying it does not take away from what you're saying at all.
In utter dark room, I targeted red laser at blue towel . I was expecting the blue towel to absorb red laser but point was visible on it. Of course the point was dimmer but was visible. Any thoughts why it didn't absorb since its a blue towel and is supposed to absorb red color?
Because blue and red are not on the opposite side of the color wheel. Red is opposite of green. Blue is opposite of orange. And violet is opposite of yellow. Try it again with these colors and see...
@@rajkaransinghgill2082 if the towel is black, chances are it was dyed black, which would mean on an atomic scale there would be some white from the cotton... Therefore some of that green light, though some of those light waves would be absorbed by the black dye, others would be reflected and you would see some green.
But can it be that transparent material is absorbing light not transmitting or reflecting it? And basically black is absorbing all colors, white is reflecting all colors and transparent is transmitting all colors? Simple as that...
When the energy gap between two energy levels in a material is large, the energy isnt absorbed and just passes through so we see the object as transparent.
It's just incorrect to say that objects are a particular colour because they absorb all the colour of the spectrum apart from one. For example, a yellow object typically reflects strong in the yellow, orange and red part of the spectrum. How is it that a company such as Edmund Scientific can get this so wrong! I am a Professor of Colour Science at the University of Leeds.
hello , thanks for the great educational videos , i have a question please : if black absorbs all colors , then how we can see clearly blue and red colors for example on a black screen ? .........thx
becouse this works on subatomic scale, and in the case of tv or somthing like that, you have the presence of another type of atoms on the black surface if its lcd ips technology, in case of older tv-s im not quite sure how they operate but i guess its even easier to explain, in case of lcd tv, you have liquid crystals all over the black screen, so the type of screen atoms are made to be black and absorb all the color wavelenghts, but the crystals have specific atomic structure and they reflect all other wavelenghts so u can actually see the colors on tv
We see objects of the colour they are because colours we can't see are absorbed by the object and the colour we can see are either pass through an object or reflected
Here's my question. So the lime isn't in actuality green? What makes it green is the fact that it's reflecting green wavelength to my eyes? I'm so confused about how colors work. 😑
@@theAntiCauliflower I think you're right. Thanks. I could have just looked up online, but I like to be surprised. Lol. Where does the heat go.. might look that up, unless you reply soon, lol
@@yourallbrainwashed Hehe no problem. I could be wrong, I haven't looked it up either - (just trying to remember back from high school Physics lessons lol). I'm pretty sure the heat gets dissipated into the surrounding air, but while the object is still hot, the thermal energy is making the molecules vibrate more ^^
The question here is why does that happen ,I mean that the black colour doesn't reflect any colour while the another colour like the blue reflects only blue , did scientists discovered why?

I wonder the objects absorb light from its atomic level or surface structure level like in the butterfly wings or it could be both.
In this example it would be atomic, or to be more specific, molecular structure.
ok so what happens to the absorbed wavelengths on the atomic level then? will the atoms absorb and release them in the form of heat or other longer invisible wavelengths? and what happens on the same level with reflection?

Absorbing light means absorbing energy. Black color objects are always absorbing light that is energy so how they remain stable in this situation ?
Absorbed light mostly goes into heating the object, and objects readily exchange heat with their environment. All else being equal, a dark object exposed to light will be warmer than a white object. Out in the sun, a blacktop parking lot will get warmer than a white cement sidewalk.
who is the best between the natural and artificial lights to identify the color of the object?
i need a answer ASAP
Do the different colors or pigments matter in terms of how light energy is absorbed?
I think so. The dark color/ pigments of the shorter wavelength violet, dark blue, light blue absorb more energy than the longer wavelengths of yellow, orange and red. We know a black, violet or dark blue shirt exposed to the sunlight of a winter day is warmer against the skin than a white, rose or yellow shirt.
