Photons

Photon is defined as the energy packet (particles having energy) originated from the source of radiation. Photons always travel in straight line with a speed of light. The energy of the photon, wavelength of the photon can be expressed as:

If the photon moves with velocity v then its realistic mass can be expressed as:

Photons are electrically neutral.
