Q. The energy distribution $E$ with the wavelength $(\lambda)$ for the black body radiation at temperature $T\ kelvin$ is shown in the figure. As the temperature is increased the maxima will
A) Shift towards left and become higher
B) Rise high but will not shift
C) Shift towards right and become higher
D) Shift towards left and the curve will become broader
Explanation
(a) According to Wien’s displacement law $\lambda_{m} \propto \frac{1}{T}$. Hence, it temperature increases $\lambda_{m}$ decreases $i.e.,$ peak of the $E - \lambda$ curve shift towards left
