1.	The solar radiation spectrumreveals that the intensitycorrespondingto a wavelength of 4750 A^(@) is maximum . Estimatethe surfacetemperature of the sun (Given Wien's constant = 2.89xx 10^(-3) m-k).
Answer» Solution :From Wien.s displacementlaw, the temperatureT ofa body CORRESPONDING to MAXIMUM intensitywave length `lambda_(m)` is givenby `T = (b)/(lambda_(m)) thereforeT = (2.89 xx 10^(-3) m - K)/(4750 xx 10^(-10)m) =6084 K` This temperaturecorrespondsto thechromsphere(SURFACE ) of the SUN.
