What is Radiation?

Radiation is energy that comes from a source and travels through space at the speed of light. This energy has an electric field and a magnetic field associated with it, and has wave-like properties. You could also call radiation “electromagnetic waves”.

What is Blackbody?

A black body is defined as the body which absorbs all the electromagnetic radiation (that is light) that strikes it irrespective of the angle of incidence and frequency of the radiation.
