31. (a) Since the electron jumps from the conduction band to the valence band, the energy of the photon equals the energy gap between those two bands. The photon energy is given by hf = hc / λ , where f is the frequency of the electromagnetic wave and λ is its wavelength. Thus, E g = hc / and λ= = ×⋅ × ×
