How much more energy does a 73 nm photon have than a 4070 nm photon? Does the 73 nm photon move at a greater speed than the 4070 nm photon? Which photon has a higher frequency? Part 1 of 4 The energy of a photon depends on its wavelength by the relation: hc Part 2 of 4 E = We have an energy relation for each photon, where subscripts 1 and 2 represent the 73 nm and 4070 nm photons, respectively. We can use these relations to express the energy of the first photon in terms of the two wavelengths and the energy of the second photon.
