(C) According to Wien's displacement law,$\lambda_m T = \text{constant}$,which implies $\lambda_{m1} T_1 = \lambda_{m2} T_2$.Given $\lambda_{m1} = 11 \times 10^{-5} \text{ cm}$ and $\lambda_{m2} = 5.5 \times 10^{-5} \text{ cm}$.We are given $T_1 = n T_2$,so $\frac{T_1}{T_2} = n$.From the law,$\frac{T_1}{T_2} = \frac{\lambda_{m2}}{\lambda_{m1}}$.Substituting the values: $n = \frac{5.5 \times 10^{-5}}{11 \times 10^{-5}} = \frac{5.5}{11} = 0.5$.Thus,the value of $n$ is $0.5$.

The maximum energy in the thermal radiation from a hot source occurs at a wavelength of $11 \times 10^{-5} \text{ cm}$. According to Wien's displacement law,the temperature of the source (on the Kelvin scale) will be $n$ times the temperature of another source (on the Kelvin scale) for which the wavelength at maximum energy is $5.5 \times 10^{-5} \text{ cm}$. The value of $n$ is:

A
$2$
B
$4$
C
