Question

what is the absorptive power of a perfectly black body?​

Answer 1

Answer:

1

Step-by-step explanation:

The absorptive power of a body or a surface is defined as the ratio of the energy absorbed in a given time to the radiant energy incident on it at the same instant of time. The absorptive power of a black body is 1 because it absorbs radiant energy of all wavelengths incident on it.
