Question

HOW IS LIGHT A FORM OF ENERGY IF THE REST MASS OF PHOTON IS ZERO?.......tell me and pls guys follow I am new here​

Answer 1

Answer:

Since photons (particles of light) have no mass, they must obey E = pc and therefore get all of their energy from their momentum. Now there is an interesting additional effect contained in the general equation. If a particle has no mass (m = 0) and is at rest (p = 0), then the total energy is zero (E = 0).
