Prove Kirchhoff's law.​

ANSWER

Heat absorbed per unit time per unit area of B = Q. As the temperature of B remains constant so in case of B also heat emitted is equal to the heat absorbed. ... Thus, the coefficient of emission is equal to the coefficient of absorption. This proves Kirchhoff's law of radiation theoretically.
