The rate at which a black body emits radiation at a temperature `T` is proportional to

A

`1/T`

B

`T`

C

`T^3`

D

`T^4`

Text Solution

Verified by Experts

The correct Answer is:
D
From Stefan’s law the rate of emission of energy per unit surface area of a black body is inversely proportional to the fourth power of absolute temperature (T) of the body.
`E = sigma T^4 (sigma = "Stefan’s constant")`
