At temperature

T

, the emissive power and absorption power of a body for certain wavelength are

e_\lambda

and

a_\lambda

respectively, then:

View answer and explanation

Correct option: C

e_\lambda=a_\lambda

Option C (

e_\lambda=a_\lambda

) is correct because, according to Kirchhoff's law, at a given temperature, the emissive power and absorptive power of a body are equal.
