photon is:​

Answer 1

Answer:

Zero Rest Mass

Explanation:

According to the special theory of relativity for any and every observer light always travels with 'c', with that being said it can be concluded that photons are never at rest. Thus, having a zero rest mass.

Answer 2

Answer:

zero mass

Explanation:

photon is, in simple terms , an elementary force carrying particle I. e. boson^2 ( obey the statisticallaw of bose - Einstein ). It has a zero mass ( rest mass) and travels at, c the speed of light vacuo.
