I was quite unsure of where to post it. First I thought of Quantum and Atomic physics. Finally I decided thermodynamics was my main concern and reasoned that classical physics might be the best place for that discussion.

I should have been clearer that it is the photon energy that I am interested in. More specifically I am interested in phenomena that is associated with heating of a material due to exposure to light (without actually exciting any electrons). Thank you for your comments about classical EM waves...

In that case I am truly confused. My textbooks and internet sources including Wikipedia often refer to shorter wavelength light as having more energy, but perhaps that designation is no more than the legacy of mechanical waves. I thought amplitude represented intensity of the light?

Hello everyone! Let me first say how cool it is that this forum exists, I wish I'd thought of coming here years ago. I am trying to understand how EM radiation works. From the high school physics that I've learned I have been under the impression that reflection was due to electrical...
