What is a black body? and how does it absorb all the frequencies?

Blackbodies absorb all light and don't emit any at thermal equilibrium, and emit thermal radiation.

According to Wikipedia, A black body is an idealized physical body that absorbs all incident electromagnetic radiation, regardless of frequency or angle of incidence. Actually, it is not necessarily to be white, but a physical body that doesn't favor certain wavelength rather than others.

So black body radiation just absorbs all light?

It is normally defined as any physical body absorbs and emits electromagnetic radiation when its temperature is above absolute zero.
