Properties of Photon
- A photon has no rest mass because it cannot be at rest with respect to an observer.
- A photon moves with the velocity of light.
- A photon is charge less particle.
- Momentum of the photon with frequency ν is:
Properties of Electron
- An electron has mass and may be at rest.
- An electron cannot move the velocity of light.
- An electron is a charged particle.
- Momentum of electron with mass ‘m’ moving with velocity ‘v’ is:
