A) 6097 K, 207 K
B) 8097 K, 307 K
C) 10,000 K. 400 K
D) 3000 K, 100 K
Correct Answer: A
Solution :
From Weins displacement law, the relation between maximum wavelength\[({{\lambda }_{m}})\]and absolute temperature (T) is \[{{\lambda }_{m}}T=constant=b\] where \[b=2.898\times {{10}^{-3}}m-K\] For sun, \[{{T}_{S}}=\frac{b}{{{\lambda }_{m}}}=\frac{2.883\times {{10}^{-3}}}{4753\times {{10}^{-10}}}=6097\,K\] For moon, \[{{T}_{m}}=\frac{b}{{{\lambda }_{m}}}=\frac{2.883\times {{10}^{-3}}}{14\times {{10}^{-6}}}=207\,K\]You need to login to perform this action.
