No. It is basic to electromagnetic theory that the rest mass is zero and the velocity in vacuum is "c". The concept of rest mass blows up when an object approaches the speed of light. This indicates that there is something wrong with Einstein's electromagnetic Theory. First it is not clear that anything in the universe is at "rest". I suspect light has a rest mass dependent on its wave length,2piRcm=nh thus m=nh/c2pi R. For a radius of 50 picometers light would weigh 7.07E-33 kg. An electron weighs .905E-30 kg or 128 times the weight of the 50 pico meter light..
What else can I help you with?
What type of mass is light?
Light 'particles' (photons) have no rest mass.
Does light from a flashlight have mass?
No, light does not have mass. Light is composed of particles called photons, which have no rest mass, but they do have momentum and energy.
Why photon has rest mass zero?
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.
Why the rest mass of photon is zero?
The rest mass of a photon is considered to be zero because photons are massless particles. They travel at the speed of light in a vacuum and do not possess rest mass. This is a fundamental property of photons in the Standard Model of particle physics.
What things are have no mass?
Light, electromagnetic radiation, and energy itself are examples of things that have no mass. These entities are composed of particles that do not have rest mass, such as photons or gluons.

No, light does not have mass. Light is composed of particles called photons, which have no rest mass, but they do have momentum and energy.
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.)
What is the mass of a 100 kg object while traveling 90 percent the speed of light?
Mass = (Rest mass) / sqrt( 1 - v2/c2 )V = 0.9 cv2/c2 = 0.811 - v2/c2 = 0.19sqrt( 0.19 ) = 0.4359Mass = (rest mass) / 0.4359 = 2.294 x (rest mass)For a rest-mass of 100 kg, that's 229.4 kg at 0.9 c .

Why photons are massless?
This refers to their so-called "rest mass", and it is related to the fact that they move at the speed of light. Any object with a non-zero rest mass couldn't move at the speed of light - if it did, its actual mass (mass, considering its movement) would be infinite.
Why gamma rays travel at the speed of light?
Because they are made up of photons, which have no rest mass. Having no rest mass, they are the only particle that is capable of traveling at the speed of light per the lorentz transformation.
When mass is decreased?
An object travelling at a velocity close to the speed of light had a higher mass than when at rest.
What fraction of the speed of light must you travel for your mass to be twice the rest mass?
To have a mass that is twice the rest mass at relativistic speeds, you would need to travel at about 86.6% of the speed of light. This is calculated using the relativistic mass formula, which states that mass increases with velocity according to the equation: m = m0 / sqrt(1-v^2/c^2), where m is the relativistic mass, m0 is the rest mass, v is the velocity, and c is the speed of light.
Why the rest mass of photon is zero?
The rest mass of a photon is considered to be zero because photons are massless particles. They travel at the speed of light in a vacuum and do not possess rest mass. This is a fundamental property of photons in the Standard Model of particle physics.
What should be the mass of anything at the speed of light?
Anything that has any mass when it's at rest would have infinite mass at the speed of light.
Can any object move with the velocity of light?
No object that has mass when it's just sitting there on the table can move at the speed of light. Photons have zero "rest mass".
