(a) Use Equation 5.113 to determine the energy density in the wavelength range and solve for .

(b) Derive the Wien displacement law for the wavelength at which the black-body energy density is a maximum:

Hint: You'll need to solve the transcendental equation , using a calculator or a computer; get the numerical answer accurate to three significant digits.
