That's related to the fact that it moves at the speed of light. If you look at the formula for mass increase as a function of speed, it should be obvious that the mass of anything that has a non-zero (i.e., positive) rest mass would approach infinity as the object approaches the speed of light - meaning that the speed of light itself can never be reached, since that would give the object an infinite mass (and require an infinite energy). The only way an object can move at the speed of light is for it to have a rest mass zero. In a way, this is hypothetical, since particles such as the photon or graviton, that move at the speed of light, can only move at the speed of light.

What is the mass of moving photon?
the mass of a photon is zero
Can mass be zero?
Just as matter is defined by having mass, there cannot be matter with zero mass. Current theories all define the "photon" (energy quantum) as having zero rest mass, although it can be treated as both a "particle" and a wave.
Why is the energy of a photon greater than that of an electron?
It does not. A photon has no rest mass an electron has mass and therefore more energy
Do photon have a greater energy than electron?
No. A photon has no rest mass an electron has mass.
What is the speed of photon at rest?
Speed = 0 The definition of "rest" is zero velocity in the observer's frame of reference. However, it's important to point out that photons don't do "at rest."
What subatomic particles have a mass of 0?
The photon. This refers to the "rest mass"; since the photon has energy, it also has an associated mass. But the "rest mass" or "invariant mass" is zero.
What do you call a particle of light with zero mass which carries a quantum of energy?
I call it a 'photon'.By the way, the photon has zero rest mass, but when it travels at the speed of light ...which it always does ... it has some mass.
What is the mass of moving photon?
the mass of a photon is zero
Why the rest mass of photon is zero in quantum mechanic?
I have a theory gw+l=gw l=m. If a gravitational warp traps photon then photon have mass. A small amount 0.000000000000000000000000001 mg. That is what i think. ============================================= Until such time as the previous contributor's hunch can be tested in the laboratory, all theory and experiment so far has shown the rest mass of the photon to be zero.
What is the mass of a photon in motion?
A photon is a massless particle, meaning it has no rest mass. Its mass is zero, but it does have energy and momentum.
A unit or quantum of light a particle of electromagnetic radiation that has zero rest mass and carries a quantum of energy?
Photon
Can mass be zero?
Just as matter is defined by having mass, there cannot be matter with zero mass. Current theories all define the "photon" (energy quantum) as having zero rest mass, although it can be treated as both a "particle" and a wave.
What is the plot mass of photon?
the photon has got 0 rest mass .and plot mass means? not knowing..
When describing photons what is rest mass?
When describing photons specifically rest mass is zero. The "rest mass" is the hypothetical mass a photon would have if it weren't moving at the speed of light, which as just stated, is zero. Nothing with a non-zero rest mass can travel at the speed of light in a vacuum, because it would require a literally infinite amount of energy to accelerate to that speed. (Neutrinos have a very small, but non-zero, rest mass, and therefore travel at most at slightly under the speed of light.)
Which particle has the least amount of mass?
The 'rest mass' of the photon is zero ... but the photon is never at rest, and it has plenty of mass at the speed of light, at which it is always traveling. so that let's the photon out. Amongst particles that actually have rest mass, but not much of it, the neutrino probably has the least.
When can a substance's mass be 0?
Yes, a Photon's mass is theorized to be zero.
Which is not the property of photon mass charge energy momentum?
A photon has zero electrical charge.
