Vedclass · Answer

(B) According to Wien's displacement law,the product of the wavelength of maximum emission $(\lambda_m)$ and the absolute temperature $(T)$ of a black body is a constant $(b)$.$\lambda_m T = b$Given:$\lambda_m = 2.93 	imes 10^{-10} \, m$$b = 2.93 	imes 10^{-3} \, m \cdot K$Substituting the values into the formula:$T = \frac{b}{\lambda_m} = \frac{2.93 	imes 10^{-3}}{2.93 	imes 10^{-10}}$$T = 10^{(-3 - (-10))} \, K = 10^7 \, K$Therefore,the temperature of the star is $10^7 \, K$.

The maximum wavelength of light coming from a star is $2.93 \times 10^{-10} \, m$. If Wien's constant is $b = 2.93 \times 10^{-3} \, m \cdot K$,what is the temperature of the star?
