In the lecture, Dr. Lavelle mentioned that the description of light as photons explains the intensity profile of black body radiation. Can someone explain what black body radiation is?

Black body radiation is a material that can absorb and emit all wavelengths of light.

The previous reply already explained what black body radiation is, but I believe during lecture that Professor Lavelle said that we don't need to worry ourselves with knowing and remembering about what black body radiation does because we will not be tested on it.

I think he also talked about how it was a theoretical concept used to explain other things? I'm a little unclear about that part.
