Question

can you explain about Black body

Answer 1

HERE IS YOUR ANSWER:-)

A black body is an idealized physical bodythat absorbs all incident electromagnetic radiation, regardless of frequency or angle of incidence. A white body is one with a "rough surface [that] reflects all incident rays completely and uniformly in all directions."[1]

A black body in thermal equilibrium (that is, at a constant temperature) emits electromagnetic radiation called black-body radiation. The radiation is emitted according to Planck's law, meaning that it has a spectrum that is determined by the temperature alone (see figure at right), not by the body's shape or composition.

Answer 2

Well there is no such thing called BLACK BODY!..

IF you mean to say it in a scientific MANNER!..


Then black body means an absorber And a radiator(energy), with no reflecting power!..

Hope this helps you out!
