Black Body Radiation

During lecture, Professor Lavelle mentioned black body radiation. What does that mean in terms of photons and light?

Well a black body is an object that "absorbs all radiation falling on it, at all wavelengths," and you can calculate the emissions with Planck's Law but I don't think we're really doing many of those calculations. I hope that kinda helped haha

I agree with Ethan, he said in class that unlike atoms and molecules which only absorb and emit unique frequencies, black bodies absorb or emit all frequencies but he said not to worry about specific calculation since black bodies are somewhat hard to understand.
