Question
The intensity of radiation emitted by the sun has its maximum value at a wavelength of 510 nm and emitted by the north star has the maximum value at 350 nm. If these stars behave like blackbodies, then the ratio of the surface temperature of the sun and the north star is
Options
A.1.46
B.0.69
C.1.21
D.0.83
Solution
From Wien′s displacement law
λm T = constant
or T =
∴
λm T = constant
or T =
∴
