Vedclass · Answer

(D) According to Wien's displacement law,the product of the wavelength corresponding to maximum intensity $(\lambda_m)$ and the absolute temperature $(T)$ of the blackbody is a constant.$\lambda_m T = b$,where $b = 2.9 	imes 10^{-3}\ mK$.From the given graph,the peak intensity occurs at $\lambda_m = 2\ \mu m = 2 	imes 10^{-6}\ m$.Substituting the values into the formula:$T = \frac{b}{\lambda_m} = \frac{2.9 	imes 10^{-3}\ mK}{2 	imes 10^{-6}\ m} = 1.45 	imes 10^3\ K = 1450\ K$.Rounding to the nearest given option,the approximate temperature is $1500\ K$.

The distribution of relative intensity $I(\lambda )$ of blackbody radiation from a solid object versus the wavelength $\lambda $ is shown in the figure. If the Wien displacement law constant is $2.9 \times 10^{-3}\ mK$,what is the approximate temperature of the object in $K$?
