A human eye is most sensitive to that wavelength( Am) at which the energy distribution of solar radiation shows the maximum. A. Apply Wien's Displacement law to calculate Am . Take the sun's surface temperature as 5800 K , and wein's constant, b = 0.29cm.K. B. Taking the average surface temperature of the earth as approximately 290K, calculate the wavelength at which it radiates most.

radiation shows the maximum.
A. Apply Wien's Displacement law to calculate Am . Take the sun's surface temperature as
5800 K , and wein's constant, b = 0.29cm.K.
B. Taking the average surface temperature of the earth as approximately 290K, calculate
the wavelength at which it radiates most.
= 5000 A°
a) For part A, Am
b) For part B, 2,m would be in infrared region of electromagnetic spectrum
c) For part A, Am = 3000 Aº
d) For part B, Am would be in visible region of electromagnetic spectrum
