That's because wavelength is inversely proportional to frequency. Violet colour has the highest frequency and lowest wavelength (which is on the left side of the graph) To conclude, it shifts to left because on increasing temperature, the oscillations of electron increases, which leads to an increase in frequency and decrease of wavelength causing the curve to shift towards the left side.
I just read about the black body radiation in the books and it was written pretty much like one in the description and I was extremely unsatisfied. Now I understood it completely. Thankyou. ❤
Wonderful animations for free of cost. Even the institute I joined by paying lakhs fails to use to digital world . But khan academy is performing some magic show using graphics for years. Thank you so much!
Sir if Electron absorbs a Photon Then acclerated by it does that mean Motion of Electron produce its own Photon And when Incident Photon releases doesn't that mean Electron gives Off Two Photon
i was actually waiting for this to come out. You know Mahesh, I really like how explain things. You are by far the best teacher i have ever had. Thanks
Is there an explicit function that describes the graph? Is the metallic box an example of a perfect black body even though we can still see it? We can see the apple because of what it’s reflecting but if it receives no electromagnetic waves then what is the color? Black? I thought black bodies were theoretical, does that mean we have pseudo black bodies? I don’t get the color connection between the stars and the black metallic box. Both are essentially black? Is there a difference between an object being red and an object shining red?
2:50 Sir... But sir the reflected red light is also due to the jiggling of electrons.. right... Then why is that some electrons do reflect red light and others reflect the thermal radiation
When you incident a ray of certain wavelength on an object, the electrons also jiggle in the same wavelength. If this wavelength is less than the threshold wavelength of the material, photoelectrons are emitted (modern physics, photoelectric effect)
That was the cleanest explanation ever
Thank you so much. You nailed it.
So good
No exaggeration you’re a life saver I never enjoyed physics as much as when you explain,respect❤❤❤❤❤
Best explanations so far of this curve.
Why does the curve drop off so fast on the left?
That's because wavelength is inversely proportional to frequency. Violet colour has the highest frequency and lowest wavelength (which is on the left side of the graph)
To conclude, it shifts to left because on increasing temperature, the oscillations of electron increases, which leads to an increase in frequency and decrease of wavelength causing the curve to shift towards the left side.
Watch it at 0.85x speed and thank me later.
I've never loved a physics explanation more. Astronomy is amazing!!

thanks mahesh for the amazing explanation !!!!
Thank you! Great explanation.

amazing loved ur teaching thanks so much 😀
amazing, please continue in quantum physics🌹🥀
That is the radiative signature of an hypersphere

Thank for this fantastic video

Because nothing is perfect
Because they vibrate at different wavelengths, and produce electromagnetic waves at diff wavelengths
When you incident a ray of certain wavelength on an object, the electrons also jiggle in the same wavelength. If this wavelength is less than the threshold wavelength of the material, photoelectrons are emitted (modern physics, photoelectric effect)
Is the jiggle in the elektrons (1:29) real or do they just absorb energy and release it without physically moving back and forth?
Electrons oscillate on receiving energy, so yes the "jiggling" or oscillations happens for real.
We can say they are vibrating..it will continue vibrating until enough energy to break/escape their bond.
this was insane 👀👍
Thank you. Now I know the temperature of ghost rider.
I love this...
Are you the one who present float head physics?
Yes :)
How you know that stars are generally black body to make such assumption
Bro so good
Wuhhhh brohhh u nailed it
Is the neutron star magnetosphere a precursor to the shedding of upper layers or occurs after 😂🧐🥴🤣
You make math fun
❤❤❤
