Question
(a) What do you understand by balck body? Draw the typical curves to show how, the distribution of energy amongst various wavelengths varies with temperature. State Wein's Law and explain how colour of a black body changes with temperature. State Rayleigh-Jeans law and its implications.
(b) The surface temperature of a hot body is $1227^{\circ}\text{C}$. Find the wave length at which it radiates maximum energy. (14, 6)
