    Incandescence and energy bands

    Got this from wikipedia but I don't quite understand what it means. From what I know regarding incandescence, it is basically the vibrational emission spectrum of a solid lattice produced when the lattice is heated up. This spectrum is continuous and contains all wavelengths of light...

    Why Does Photon Energy Calculation Yield Different Results?

    Homework Statement Find the momentum and energy of photons of light of wavelength 500nm. Usual data of h = 6.63 x 10-34 and c = 3.0 x 108ms-1Homework Equations The Attempt at a Solution > To get momentum, i simply take momentum = h/wavelength = 1.326 x 10-27 kgms-1 > To get energy I use E =...
