Simply Magnificent, during classes of Physics and Science I paid little to no attention due to my lack of sleep and teachers that lacked the enthusiasm to help me find the passion for it but this video just hits the dopamine for information collected online
Great content. Really don't understand why more people don't watch this stuff. You never really completely understand science at high school level and I for one really need these kinda videos to help. Thanks man
WOW ... This is explained so nicely and clearly ! I wish I had access to this growing up, the confusing math and physics and science could have been really awesome and fun sessions ... I guess the kids today are lucky in that sense ... Keep up the great work and thanks
Woah this is too good! Thank you so much!!!! The best video on this subject so far, a comprehensive, and well-explained introduction with amazing animation! Absolutely brilliant! Thank you for all that you do, it is very much appreciated. Got that "ah, I see!" moment finally.
For the ones curious, I leave here a explanation of why refraction happens: (It can be explained as a consequence of conservation of momentum of photons) If in medium 1 the index of refraction is n1 and in medium 2 the index of refraction is n2 and for the definition of index of refractions and wavelength we have: n1 = c / v1 , v1 = λ1 * f n2 = c / v2 , v2 = λ2 * f Dividing the above equations we obtain: n2 / n1 = λ1 /λ2 So if n2 is higher than n1, the wavelength in medium 2 is smaller than in medium 1. Now because the photon momentum is: p = h / λ Applying the conservation of momentum of the incident and transmitted photon along the parallel line of medium separation: p1 = p2 → h/λ1 *sin(θ1) = h/λ2 *sin(θ2) → n1 *sin(θ1) = n2 *sin(θ2) This is the Snell Law!! So the light bending is just a consequence of the conservation of momentum of photons!
this was so helpful and in school they just dont teach it this way.have you ever considered teaching or taking classes by any chance? i think you could really help other people understand too
But I thought that light always traveled at the speed of light. I thought that was an intrinsic property of light, that photons only can move at light speed. Or is that totally wrong?
Do this tells me that light rays have a thickness.. cause one end of a light way must enter the new medium first then the other ends follow. How thick is a light ray?
So does this mean refraction is a form of diffraction, where a wavefront pivots around an object (in this case, the material interface)? What's a good way to picture how this wavefront looks then? I guess maybe if we think about a wavefront impacting a surface at an angle, the first part of the wavefront to impact will 'stop' and allow different phases of the wave to 'catch up' further down the surface; so it appears that the direction of propagation of the lines of the waves becomes more normal to the surface, and constructive/destructive interference basically recreates the waves inside the material as if they had all entered from this more-normal angle. so the angle of refraction is 'how far back' in the wave phase the difference in arrival times at the surface causes the wave front to be out of phase
This was extremely informative until i saw the ending where you used a focal lense and the middle ray of light (indicent Ray) exited the same path as the incident ray but was the emergent ray why is that.
I see these.. but no one ever since explains ehat happens if you open up the angle of incidence.. what affect that has on the refracted ray? Is it always the same? Does that angle change with material?
No, this is an incorrect explanation. They say "...for a short period of time the other wheels continue at a faster speed" People, light CANNOT travel faster than the speed of light. The light can't just speed up on the outside while its passing into a denser medium.
It's a capital letter at the beginning of sentences plus an apostrophe ("its" should be It's) and a "period/." at the end of the sentence. It should also be a capital t (The) and insert "is" before silent (not silence), followed by another period (.). Waer is the pronunciation in some countries/regions. Before you attempt to become a pronunciation/grammar police, please improve yourself first. You need a lot of it.
I didn’t understand this in school but thank you for this video! It helped me understand way better and now I think I’ll be fine in the test I have coming up soon.
Thank you so much! All of the other videos immediately jump into the formulas and the others doesn't even scratch the surface of refraction. This video helped me so much. Thank you! I do hope you make a video about the laws of refraction soon. I really love the way you explained this. Thank you again!

Thanks I’m glad you’ve found it so useful.
We watched this at school but I didn’t quite understand refraction so I watched it again at home and now understand!

For the ones curious, I leave here a explanation of why refraction happens:
(It can be explained as a consequence of conservation of momentum of photons)
If in medium 1 the index of refraction is n1 and in medium 2 the index of refraction is n2 and for the definition of index of refractions and wavelength we have:
n1 = c / v1 , v1 = λ1 * f
n2 = c / v2 , v2 = λ2 * f
Dividing the above equations we obtain: n2 / n1 = λ1 /λ2
So if n2 is higher than n1, the wavelength in medium 2 is smaller than in medium 1.
Now because the photon momentum is: p = h / λ
Applying the conservation of momentum of the incident and transmitted photon along the parallel line of medium separation:
p1 = p2 → h/λ1 *sin(θ1) = h/λ2 *sin(θ2) → n1 *sin(θ1) = n2 *sin(θ2)
This is the Snell Law!!
So the light bending is just a consequence of the conservation of momentum of photons!
Now I’m more confused
No one cares g 🤡
Thank you! That's so cool!!!!!!!!!!!!!!!!!!!!!!!!
POV: your here cause of physics
Here because it’s a lesson I’ve been set lol
I am though...
Same rn....for lesson..
Same XD

Wow thank you so much your car explanation was genius and really helpful to me thank you so much!
yassssss
Ur profile picture is the same as a sticker I have ur famous lol
Yes I have to admit, this, was good. Even I could understand it and that's not an easy thing to achieve. You have a new Subscriber sir. Thank you.
the analogy with the car definetly helped me understand this a lot better! thank you for the VISUAL this video is awesome
this was so helpful and in school they just dont teach it this way.have you ever considered teaching or taking classes by any chance? i think you could really help other people understand too
ive watched 4 videos on refraction and this one takes the cake. Thanks a lot
Bro the car example hits different for me. I love you for this. Thank you so much.
Does the object that the light is refracting off of get birghter the closer you get to it?
Damn! That's a magnificent level of detail. Thank you for sharing it.
But I thought that light always traveled at the speed of light. I thought that was an intrinsic property of light, that photons only can move at light speed. Or is that totally wrong?
Great video!!! This helped me understand refraction. The car explanation was perfect!
Do this tells me that light rays have a thickness.. cause one end of a light way must enter the new medium first then the other ends follow. How thick is a light ray?
So does this mean refraction is a form of diffraction, where a wavefront pivots around an object (in this case, the material interface)? What's a good way to picture how this wavefront looks then? I guess maybe if we think about a wavefront impacting a surface at an angle, the first part of the wavefront to impact will 'stop' and allow different phases of the wave to 'catch up' further down the surface; so it appears that the direction of propagation of the lines of the waves becomes more normal to the surface, and constructive/destructive interference basically recreates the waves inside the material as if they had all entered from this more-normal angle.
so the angle of refraction is 'how far back' in the wave phase the difference in arrival times at the surface causes the wave front to be out of phase
I graduated high school 14 years ago, now I'm re-studying it again. Gosh, school education is such a sham.
should use ya diff locks so you dont turn when ya hit the sand
Extremely good explanation
best video on the subject by far, thank you 🙏
This was extremely informative until i saw the ending where you used a focal lense and the middle ray of light (indicent Ray) exited the same path as the incident ray but was the emergent ray why is that.

Here from online class

yup
Except light is not waves. And why should the light exiting the water resume its original path, in the same angle? No explanation.
It seems make sense but it's WRONG! You need Maxwell equation to explain why light change direction.

No, this is an incorrect explanation.

People, light CANNOT travel faster than the speed of light.

I think he meant faster than the light that had slowed down
