A) \[{{\lambda }_{m}}T=\]constant
B) \[\frac{{{\lambda }_{m}}}{T}=\]constant
C) \[{{\lambda }_{m}}\sqrt{T}=\]constant
D) \[\frac{{{\lambda }_{m}}}{\sqrt{T}}=\]constant
Correct Answer: A
Solution :
In the spectral distribution of energy emitted by a black body maintained at different temperatures, the product of wave\[{{\lambda }_{m}}\] corresponding to maximum radiant energy arid temperature T is constant or\[{{\lambda }_{m}}T=\] constant (Wiens constant).
