According to the Planck theory of black-body radiation, the radiant spectral emittance is given by the formula

where λ is the wavelength of the radiation, h is Planck’s constant, k_B is Boltzmann’s constant, c is the speed of light, and T is the temperature on the Kelvin scale. Treat T as a constant and find an equation that gives the wavelength of maximum emittance.
