Question

state and prove kirchoffs law of heat radiation ​

Answer 1

Answer:

Kirchoff's law states that the ratio of the emissive power to absorptive power for the radiation of a given wavelength is constant for all substances, at the same temperature. ... Amount of radiation absorbed by body per second per unit area = aλ Q. The body is in thermal equilibrium with the enclosure.
