No words to explain your work.

[@PhysicsAddhyan]

Thanks shubham

[@muktarahmed9746]

Thank you sir, So u discussed about 1. Photoelectric effect. 2. Compton effect. 3. Black body. ~ In this video Now I waiting for your next valuable video as it is. . Shukriya

[@PhysicsAddhyan]

Sure, next video soon.

[@tapanjyotisharma8203]

thank you very much...hoping some more lecture on QM and problems related with it..

[@kartikkalia01]

These question awsome and the best part is youare doing all this free. Respect for you man!

[@PhysicsAddhyan]

Thanks

Thank you sir very helpful

[@balajivs69]

Sir, can u please make a separate video of all the important and shortcut formulas of main topics. Please. Only main topics.

Thank you so much sir.

20:39 but energy density vary with (frequency)^3 not (frequency)^5, plancks law.

[@PhysicsAddhyan]

Thanks shubham for pointing out the error.

Rahul Sir, I have a little doubt. It's specified in JAM's syllabus that we only need to do the solution of Schrodinger's equation for Infinite potential well, harmonic oscillator and step function, But almost every material I've studied, be it HCV, Griffiths even MIT-OCW always solve SE for a couple other cases, namely Free particle and Dirac delta function. I also get that finite step is a special case for Dirac delta function. So my question is, Do I really need to bother with the potentials which are not given in the syllabus?

[@PhysicsAddhyan]

If you have studied some advanced topics, that's good. They will help you indirectly. They will be asked in JEST examinations

[@bharti4679]

Sir are these questions important for JAM 2021 also?

[@afhamahammed9662]

Are you sure the formula for ke of compton scattered electron is accurate. Is there a 1/2 missing in the second term of the denominator?. Can you please post the derivation for this formula.

[@PhysicsAddhyan]

I have replied your question in telegram group.

[@quantization_1234]

Sir, we know that in photoelectric effect photo current depends only on the intensity of incident light, not on frequency. But in 1st problem we see that photo current increase with decrease of frequency though the intensity remain constant .... Is not it a contradiction? Please help me to remove my doubts or misconceptions

[@PhysicsAddhyan]

Yes, you are correct only when you vary the intensity for fixed frequency. But here the problems given is for constant intensity and vary the frequency then how the current changes. Just opposite case.

@@PhysicsAddhyan now it is clear to me, thank you so much sir....your beautiful teaching inspires me and also helps me to understand concepts easily.
