A)Photon A is traveling twice as fast as photon B.
B)Both photons have the same speed.
C)Both photons have the same wavelength.
D)The wavelength of photon A is twice as great as the wavelength of photon B.
E)The wavelength of photon B is twice as great as the wavelength of photon A.

All photons travel at the same speed in a vacuum, which is the speed of light, so both photons have the same speed. The momentum of a photon is inversely proportional to its wavelength, so if photon A has twice the momentum of photon B, then the wavelength of photon B is twice as great as the wavelength of photon A.

Photon a Has Twice the Momentum of Photon B as Both
