What is difference between photon and electron?

Properties of Photon

  1. A photon has no rest mass because it cannot be at rest with respect to an observer.
  2. A photon moves with the velocity of light.
  3. A photon is charge less particle.
  4. Momentum of the photon with frequency ν is:

P=hν/c

Properties of Electron

  1. An electron has mass and may be at rest.
  2. An electron cannot move the velocity of light.
  3. An electron is a charged particle.
  4. Momentum of electron with mass ‘m’ moving with velocity ‘v’ is:

P=mv
