Wein's displacement law states
Options
- A( _m T= ) constant
- B( _m T = ) constant
- C( T _m = ) constant
- D( _m+T= ) constant
Correct answer
A. ( _m T= ) constant
Step-by-step solution
According to Wien's displacement law, the wavelength ( ( _m ) ) corresponding to which the energy emitted by a black body maximum is inversely proportional to its absolute temperature (T). i.e., ( _m 1 T ) ( _m= b T ) [where, (b= ) Wien's constant] ( _m T=b )
