Question

If the wavelength of maximum intensity of radiation emitted by sun and moon are 0.5× 10- 6 m and 10-4 m respectively, the ratio of their temperature is (A) 1: 100 (B) 1: 200 (C) 200: 1 (D) 400: 1

(T1/T2)=n=(λ m2/λ m1)= (10- 4/0.5 × 10- 6)=200

Q. If the wavelength of maximum intensity of radiation emitted by sun and moon are $0.5 \times 1 0^{- 6}$ $m$ and $1 0^{- 4}$ $m$ respectively, the ratio of their temperature is

1 : 100

1 : 200

200 : 1

400 : 1

$\frac{T _{1}}{T _{2}} = n = \frac{λ _{m_{2}}}{λ _{m_{1}}} = \frac{1 0 ^{- 4}}{0.5 \times 1 0 ^{- 6}} = 200$
