How does a photon have momentum without mass

WebThe photon must be near a nucleus in order to satisfy conservation of momentum, as an electron–positron pair produced in free space cannot satisfy conservation of both energy and momentum. [4] Because of this, when pair production occurs, the atomic nucleus receives some recoil. The reverse of this process is electron–positron annihilation .

Why Do Photons Not Have Mass? (Simple Proof)

WebJan 12, 2015 · Mass and kinetic energy are only two of several properties that a fundamental quantum object can carry. Saying that light is "pure energy" would imply that light only carries the property of energy and no other properties, which is simply not true.
