Question

If wavelengths of maximum intensity of radiations emitted by the sun and the moon are $0.5 	imes 10^{- 6}m$ and $10^{- 4}m$ respectively, the ratio of their temperature is

Dr. Abubacker · Accepted Answer

(d) $\lambda_{m}T =$ constant $\Rightarrow \frac{T_{1}}{T_{2}} = \frac{\lambda_{2}}{\lambda_{1}} \Rightarrow \frac{10^{- 4}}{0.5 	imes 10^{- 5}} = 200$
