Solar radiation emitted by sun resembles that emitted by a black body at a temperature of 6000K. Maximum intensity is emitted at a wavelength of about 4800A°. If the sun was cooled down from 6000 K to 3000 K then the peak intensity would occur at a wavelength of ______? Answer: 9600A˚

If the sun cooled to 3000 K, the peak intensity would occur at a wavelength of 9600 A°. This is determined by Wien's displacement law, which describes the inverse relationship between a black body's temperature and its peak emission wavelength.
