PhysicsThermal Properties of MatterMHT CET

Solar radiation emitted by sun resembles that emitted by a black body at a temperature of 6000 K. Maximum intensity is emitted at a wavelength of about 4800 Å. If the sun were cooled down from 6000 K to 3000 K, then the peak intensity would occur at a wavelength of

Answer: (B)

Solution

Wien's law constant, so halving doubles to 9600 Å; 4800 Å ignores
