(A): A body that is a good radiator is also a good absorber of radiation at a given wavelength.
(R): According Kirchoff's law the absorptivity of a body is equal to its emissivity at a given wavelength.

View answer and explanation

Correct option: A

If both A and R are true and R is the correct explanation of A
