Given:
The wavelength of maximum intensity of radiation emitted by sun and moon are 0.5 x 10^-6 and 10^-4 respectively.
To find:
The ratio of their temperature:
Solution:
From given, we have,
The wavelength of maximum intensity of radiation emitted by sun is 0.5 x 10^-6
The wavelength of maximum intensity of radiation emitted by moon is 10^-4
we use the formula,
Ts/Tm = λm/λs
Ts/Tm = 10^-4 /0.5x10^-6
Ts/Tm = 200
Therefore, the ratio of temperature of sun and moon is 200.
