A particular star (assuming it as a black body) has a surface temperature of about $5 \times 10^{4} \mathrm{K}$. The wavelength in nanometers at which its radiation becomes maximum is (b = 0.0029 mK)
Text Solution
Verified by ExpertsThe correct answer is:
B
According to Wein’s displacement law
$\lambda_{m} \mathbf{T} = \mathbf{b}$ or $\lambda_{m} = \frac{b}{T} = \frac{0.0029}{5 \times 10^{4}} = 58 \times 10^{-9} \mathrm{m} = 58 \mathrm{nm}$
