Thermal Radiation: Black Body, Stefan & Wien

' $x$ ' joule of heat is incident on a body. Out of it, the total heat reflected and transmitted by it is ' $y$ ' joule. The absorption coefficient of the body is

Show answer and solution

Answer: (b)

Heat absorbed $= x - y$ (rest is reflected or transmitted).
$a = \dfrac{\text{absorbed}}{\text{incident}} = \dfrac{x-y}{x}$
So the answer is (b).
