The power radiated by a black body is P ...

The power radiated by a black body is P and it radiates maximum energy at wavelength, `lambda_(0)`. If the temperature of the black body is now changed so that it radiates maximum energy at wavelength `(3)/(4)lambda_(0)`, the power radiated by it becomes nP. The value of n is

A

`(256)/(81)`

B

`(4)/(3)`

C

`(3)/(4)`

D

`(81)/(256)`
