1.	The solar radiation spectrum reveals that the intensity corresponding to a wave length of 4750 A^(@) is maximum. Estimate the surface temperature of the sun (Given Wien's constant = 2.89xx10^(-3)m-K)
Answer» Solution :From Wien.s displacement law, the temperature T of a body CORRESPONDING to maximum intensity wavelength `lamda_(m)` is GIVEN by `T=b/lamda_(m)" "thereforeT=(2.89xx10^(-3)m-K)/(4750xx10^(-10)m)=6084K` This temperature is corresponding to the CHROMOSPHERE (surface) of the sun.
