Question:-
~~~~~~~~~
Difference b/w thermal radiation and black body radiation?

Answer
~~~~~~~

Thermal radiation:- it is the radiation that is produced inside material bodies and gets more intense with higher temperature.
€. its frequency spectrum depends on the temperature and composition of the body. €. The body does not need to be in thermodynamic equilibrium, it suffices that its elements can be assigned local temperature.
€. The spectrum often shows characteristic peaks and holes (liquids, solids) but universally drops to zero for zero and infinite frequency.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Black body radiation :- Black body is an ideal body which emits and absorbs radiation of all frequencies the radiation emitted by these bodies are called black body radiation />____________________________________________________________/>Hope It helps

Answer 2

All objects with a temperature above absolute zero (0 K, -273.15 oC) emit energy in the form of electromagnetic radiation. A blackbody is a theoretical or model body which absorbs all radiation falling on it, reflecting or transmitting none.
