I want lecture notes of your prof :) if you want any educational material, try me, i might have that too original stuff.

i have read calculus till that level, but in my profession i never needed it, therefore over years i forgot them all. Ofcourse there is no best book, but can you guide me to one book that you prefer; or all the books. I have capacity to read, so that is not a problem.

Fully agreed, can you suggest the best book on thermal radiation.

I do not know this much maths :) but I can understand it somewhat. That is why I was trying to do qualitatively.

Excellent point, but so sorry I never did that. But I understand that the if the temperature is same, then be it be red light or blue light, heat radiated should be same. Am I right on this?

thank you for your replies, it was really very helpful.

thank you for replying I have seen the derivation; the integration was done from 0 to ∞. Thus, it means that the sum of intensity of all wavelengths comes out to be P = σAT4 for a black body. Now, when i take a body which is not a black body (let me call it a grey body), then the result will...

thank you for reply A very nice and clear answer. I understood that, but i have a different question. I have confusion regarding use of formula P = σεAT4. Suppose there is a general body; and radiations of particular band of spectrum are falling on it. Then the power absorbed by it is P...

Please comment if i am right? The way i understood this is: 1) When a electromagnetic spectrum falls on a body which is NOT a black body, then some photons are reflected back completely. 2) in cavity radiation, when light enters the cavity, the photons those are reflected by the walls of the...

I was wondering about the spectral radiancy curve of a black body. How does the spectral radiancy of any other body looks like. I have seen one among many possibilities: http://www.giss.nasa.gov/research/briefs/schmidt_05/ Q 1. But i was thinking that for a general body (not a black body)...
