Question:
Does a photon, like a moving particle such as an electron, have a momentum?
(a) No, because a photon is a wave, and a wave does not have a momentum.
(b) No, because a photon has no mass, and mass is necessary in order to have a momentum.
(c) No, because a photon, always traveling at the speed of light in a vacuum, would have an infinite momentum.
(d) Yes, and the magnitude p of the photon’s momentum is related to its wavelength λ by p = h/λ, where h is Planck’s constant.
(e) Yes, and the magnitude p of the photon’s momentum is related to its wavelength λ by p = hλ, where h is Planck’s constant.
