Relation between emissivity e and absorptive power a is (for black body)

What is the relation between the emissivity and absorbing power of a black body?

At a given temperature the ratio between emissive power and absorptive power is same for all bodies and is equal to the emissive power of black body This statement is called .

Distinguish between Emissive power and absorptive power.

The graph shown in the adjacement diagram represents the variation of temperature (T) of two bodies x and y having the same surface area, with time (t). Both of these bodies lose heat only due to the emission of radiation. Find the correct relation between the emissive and absorptive power of the two bodies.

The absorptive power of a black body is _____.
