Question

what is the value of mass of photon​

Answer 1

• The photon's rest mass is zero. The concept of the rest mass derives from special relativity.

• The rest mass is the mass of a particle (in our case the photon) as measured by an observer who sees the particle still and with zero speed.

• In other words, the particle is at rest as far as this observer is concerned.
