A heated body emits radiation which has maximum intensity at frequency `v_m` If the temperature of the body is doubled:

A

The maximum intensity radiation will be at frequency `2V_(m)`

B

The maximum intensity radiation will be at frequency `(1//2)V_(m)`

C

The total emitted energy will increase by a factor of 16

D

The total emitted energy will increase by a factor of 2.

Text Solution

Verified by Experts

The correct Answer is:
AC
According to Wien’s law, `lambda_(m)T` = constant or `(T)/(v_(m))` = constant
So, if T is doubled, `V_(m)` is also doubled.
Further, according to Stefan’s law `EpropT^(4)` ,
When T is doubled, E increases by a factor of 16.
