Suppose u()d is the energy density per unit volume emitted by a black body in the wavelength

Suppose u(λ)dλ is the energy density per unit volume emitted by a black body in the wavelength range λ to λ +dλ. At what wavelength does u(λ) have its maximum value? Take the radiation from Sun to be black body radiation with a maximum in u(λ) at 480nm. What is the temperature of the Sun?
