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
Answer & Solution
Correct Answer
(B) Wien's displacement law
Step-by-step Solution
Detailed explanation
The surface temperature of the stars is determined using Wien's displacement law.
According to this law, \(\lambda_{m} \mathrm{~T}=\mathrm{b}\)
where \(b\) is Wien's constant whose value is \(2.898 \times 10^{-3} \mathrm{mK}\)
According to this law, \(\lambda_{m} \mathrm{~T}=\mathrm{b}\)
where \(b\) is Wien's constant whose value is \(2.898 \times 10^{-3} \mathrm{mK}\)
