उत्तर

A perfect black body has an emissivity value of 1.

Explanation:

Emissivity (e) is a measure of how efficiently a body emits thermal radiation compared to an ideal black body. For a perfect radiator (black body), e = 1, meaning it emits the maximum possible radiation at a given temperature.
