Q. The surface temperature of the stars is determined using
A) Planck’s law
B) Wien’s displacement law
C) Rayleigh-Jeans law
D) Kirchhoff’s law
Explanation
(b) The surface temperature of the stars is determined using Wien’s displacement law. According to this (law)$\lambda_{m}T = b$ where $b$ is Wien’s constant whose value is $2.898 \times 10^{- 3}$ mK.
