Unformatted text preview: he same energy. At what value of energy (in eV) will the wavelength of the photon be 10 times that of the electron. The wavelength of the photon will be given by the formula in the last problem, Emin = Ew = λ photon = hc
hc . → λmax =
λmax
EW hc
, E while that for the electron is given by the de Broglie relation Thus, when the photon wavelength is 10 times the electron wavelength, we have or and E = 10...
