To derive the blackbody spectrum, we set up the situation by assuming that a cavity is in thermodynamic equilibrium with a heat bath.
My questions are:
1) Is the heat bath the black body?
2) Why is it called a blackbody?
3) Why does the cavity have to be in thermal equilibrium with the heat bath?
4) Where in the derviation of the spectrum are the assumptions of a heat bath and thermodynamic equilibrium and cavity incorporated?
