Black Body Radiation (1 Viewer)

[Dragie]

I was just reading through Ideas to Implementation so I'm familiar with it when we get back from the holidays and I don't think I fully understand black body radiation. I get the basics and that it is something that absorbs radiation but that's about where my understanding stops...
Also a cathode ray tube...what exactly does it do and what is it?

Thank you so much

Cathode Ray Tubes - evacuated (i.e., removed of almost all air) glass tubes which contain two electrodes, a cathode (negative) and an anode (positive). When a significantly large potential is applied across these two electrodes, a stream of electrons flows from the cathode to the anode. It was the study of these so-called "rays" that led to electrons being incorporated into the model of the atom.

Black Body Radiation is significantly more difficult to understand, hence it is only an identify dotpoint. Just make sure you know what the radiation is, know what a black body is, and also that classical physics could not explain it. Try this link:
