If wavelengths of maximum intensity of radiations emitted by the sun and the moon are $0.5 \times 10^{-6} \mathrm{m}$ and $10^{-4} \mathrm{m}$ respectively, the ratio of their temperatures is
Text Solution
Verified by ExpertsThe correct answer is:
D
$\lambda_{m}T=\text{constant} \Rightarrow \frac{T_{1}}{T_{2}}=\frac{\lambda_{2}}{\lambda_{1}} \Rightarrow \frac{10^{-4}}{0.5 \times 10^{-5}}=200.$
