This guy is great. It is good to see that he is now venturing into the realm of quantum mechanics. I still say no one has better "Chalkmanship" than this guy.
Extremely helpful, compact and comprehensive video. May Allah bless you. Politely request to make a comprehensive video on pair production and pair anhilation. Thanks alot!!!!!
Sir u r great I have no such words to elaborate my feelings how u made this topic easy to digest for me .lots of respect from Pakistan. May God bless u
Sir, please make a video on solving schrodinger equation for triangular potential well (using power series solution of airy's differential equation). This question is asked in many interviews. This would be really helpful since nobody on YT has made it yet.
Professor!, in an interaction of a photon with a free stationary electron, is it possible to predict the scattering angle of the photon? Or to predict a probability distribution of this scattering angle? Predict it only in terms of the initial state of the system.
Aslmualikm.. Sir plz tell me the Anwer of this question.. Q. Why we have high intensity peak of scattered Photon compared to original x rays Photon... I mean peak to peak...
Because of Heisenberg uncertainty principle we couldn't dedect position and momentum of an electron simultaneously. Thus we can not predict before collision of electron and photon.
Once again an excellent exposition (the best RUclips version) by Professor Das. I would like to inquire--one needs an excellent monochromator for the X-rays (as the wavelength shift is very small) and is there a way to predict the intensity profile vs the wavelength?
Terrific lecturer. Explains topic very well, clearly and concise. I do have a question. How can a scattered electron obtain a velocity of the speed of light by colliding with a single photon?
i think electron would not have speed of light, or if it does then it must be moving around nucleus at that speed, photon just give it other direction while colliding. in fact in current, electron just move by micro or nano meter, it is wave which travel speed of C
The energy of the photon hf is observed completely by the electron in photoelectric effect. But in Compton effect the photon transfers only part of its energy to electron and scatters with less energy. Doesn't seem contradictory? Could you please explain the physics behind this..
I think the reason is the if you want to take out the electron from the atom you need to provide a certain amount of energy .. otherwise it won't get out of the atom.. but in collision there is no such restriction..
@@Pavan_Gaonkar I too think the same infact in photoelectric effect photon's energy must cross certain threshold energy but in Crompton scattering there is no such conditions
But the question arises that for high energy photon Crompton scattering is dominant so which one happens photoelectric effect or Crompton scattering? (The photon energy is above the threshold energy)
If you remember in P.E.E we have a work function of emiter and to emitt electrons energy of incident photon should be greater ,but here there is no such condition , and we also have x and gamma rays that cause comptons effect ,it s that only x and gamma rays cause comptons effect
Hi there, I just wondered why many people seem to imply it's the 'hits per second' that counts as 'higher energy' instead of a single wave / photon approach which would be the acceleration curve of the wave on the electron. Frequency is not a good term to use in conjunction with the photoelectric effect to me as it locks in the idea of multiple waves needed to free an electron, instead of one short wave = very fast electron acceleration.. I know it's a convention and makes sense from a wave beam / oscillating system point of view but not photonically. More photon hits should produce more electron photons if the incoming photons are above the atom's energy threshold.
thanks for your videos , i have a question plz , about the Probability of compton effect , it dominates with high photon energy over photoelectric effect , then why its probability decrease with the increase of photon energy ? ,tried to search but felt confused , Thanks for your help
So effortessly you have derrived the equation. I have looked at others and a couple of text books too but they all just jump from one equation to the other by just mentioning "algebraic manipulation" 😄 .. That shows either they are lazy and dont care about the details or they just dont know. Thanks a lot!!
@@FortheLoveofPhysics why so because in the upward motion, it is upstream for the object and for the downward motion it is downstream then how came the both time equal
@@FortheLoveofPhysics Why light doesn't bend while passing through optical centre? Why does light bend on refraction Why does light slows when it enters an optically denser medium from an optically rarer medium?
Hello sir I am a JEE aspirant i iam following your concept video for grasping indepth of jee syallabus topics. Can you make a video on Uniqueness theorem (Electrostatics) jee advanced Point of view 😅😅😅
This is a nice mathematical shortcut, but unfortunately for Compton, we know that electrons can not absorb fractions of photons. The math might work out right, but the physics here can not be correct.
@@FortheLoveofPhysics Yes, that was Compton's theory, but as I said, we know that can not happen. Also, you use a stationary electron for an example, and we know that can not happen either. The billiard analogy is like Bohr's planetary model of the atom. It works as a mathematical tool, but it is not an accurate model of reality.

Great explanation,, I am end up with easy derivation 🎉❤
sir you way of explaining is really awesome
Great explanation sir 💐
Nice explanation sir 😊
Thank you for your awesome teaching!
Awesome video! Great explanation!
I am not able to understand why Compton effect is elastic or inelastic collision. Can you please explain ? Your lecture is really awesome.
Sir is there any effect where Photon interacts with electron which also shows ' Standing Wave '?
Sir literally thank you just thank you
Another brilliant lecture
Excellent teacher you are!!
Better explanation ever
Sir... Please make a series on General theory of relativity after Quantum mechanics series... General theory of relativity is important.
Thank you so much sir.

.Is Compton scattering elastic or in elastic . Why? Full details
Sir I want this answer. Plzzzz. Helppp
Inelastic scattering, as incident radiation loses energy in the scattering process
So effortessly you have derrived the equation. I have looked at others and a couple of text books too but they all just jump from one equation to the other by just mentioning "algebraic manipulation" 😄 .. That shows either they are lazy and dont care about the details or they just dont know. Thanks a lot!!
37:00 . fractional loss in KE
If an object is thrown vertically upwards,then will the time taken to go up will be same as time taken to come down or will it be different?
In the absence of drag, time taken will be same
@@FortheLoveofPhysics why so because in the upward motion, it is upstream for the object and for the downward motion it is downstream then how came the both time equal
@@FortheLoveofPhysics Why light doesn't bend while passing through optical centre?
Why does light bend on refraction
Why does light slows when it enters an optically denser medium from an optically rarer medium?
@@FortheLoveofPhysics in case of refraction does change in direction of light (bending )of light has anything to do with change on speed of light
Thankyou sir
Thanks
I think the collision is elastic in Compton effect. He is saying inelastic . Very Confusing?
It's an inelastic scattering, as the photon loses energy
After watching this lecture after 8 months, i feel reloaded😅😅😅
sir is this why we are getting slow signal of 5G because it uses high energy micrometre wavelength radiation?
