Question:

10.1 Let (λ,T )dλ be the energy density per unit volume in the wavelength range λ to λ+ dλ of black-body radiation at temperature T. At what wavelength does the wavelength spectrum (λ, T) have its maximum value?

The radiation emitted by the sun has very nearly the spectral distribution of black-body radiation. If the maximum intensity per unit wavelength occurs at a wavelength of 4800 Å what is the temperature of the surface of the sun?
