Which of the following is true about the momentum of photons?
Photons have no rest mass, so they have no momentum.
The momentum of a photon is directly proportional to its energy.
The momentum of a photon is inversely proportional to the square root of its frequency.
Photons all travel at the speed of light, so they all have the same momentum.
The momentum of a photon is directly proportional to its wavelength.
