The total emissivity power is defined as the total amount of radiation emitted by a black body per unit
Right Answer is:
Time
SOLUTION
Total emissive power is defined as the total amount of radiation emitted by a body per unit time.
Emissivity is defined as the ratio of the total emissive power of a body to the total emissive power of a black body. It is denoted by ϵ.
ϵ = E/Eb
