A heated body emits radiation which has maximum intensity near the frequency v_{0}. The emissivity of the material is 0.5. If the absolute temperature of the body is doubled,

(a) the maximum intensity of radiation will be near the frequency 2v_{0}

(b) the maximum intensity of radiation will be near the frequency v_{0}/2

(c) the total energy emitted will increase by a factor of 16.

(d) the total energy emitted will increase by a factor of 8.
