The frequency `(v_(m))` corresponding to which energy emitted by a black body is maximum may very with temperature T of the body as shown in figure. With of the curves represents correct variation ?

Options

A. A
B. B
C. C
D. D

Answer

A

Explanation

According to Wien 's displacement law,
`lamda_(m)prop(1)/(T)" or "(C)/(v_(m))prop(1)/(T)`
`"i.e " v_(m)propT`
Hence , curve A represents the correct variation.
