Question

rest mass of a photon is zero is its momentum also zero?​

Answer 1

Answer:

It has been clearly established that the photons, if at all at rest, would have zero mass and hence, zero momentum.

However, photons can never be arrested. This would mean that photons do possess definite momentum by virtue of their motion. They always keep moving with a velocity equal to that of light.

hope it helps!!

Answer 2

Answer:

Yes,momentum will also be zero.
