Answer:
The answer is then definitely "no": the photon is a massless particle. ... Sometimes people like to say that the photon does have mass because a photon has energy E = hf where h is Planck's constant and f is the frequency of the photon. Energy, they say, is equivalent to mass according to Einstein's famous formula E = mc2
Explanation:
mass of a photon is always zero since photons are continuously moving at the speed of light

Answer:
The answer is then definitely "no": the photon is a massless particle. Even before it was known that light is composed of photons, it was known that light carries momentum and will exert pressure on a surface. This is not evidence that it has mass since momentum can exist without mass.
