A heated body emits radiation which has maximum intensity at frequency `v_(m)`. If the temperature of the body is doubled :

Options

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.

Answer

AC

Explanation

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.
