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.
No, photons are not considered to be a form of matter. They are massless particles that carry electromagnetic energy.
Massless particles traveling at the speed of light include photons, the particles of light. They have no rest mass and always move at the speed of light in a vacuum according to the theory of special relativity.
No, light does not have mass. It is made up of particles called photons, which are massless.
The three lightest subatomic particles are electrons, neutrinos, and photons. Electrons and neutrinos have very small masses, while photons are massless.
sunlight is a particle of energy called a photon. photons are massless and are not a material in the conventional sense.
The significance of momentum for a massless particle is that it determines the particle's energy and direction of motion. Since a massless particle always travels at the speed of light, its momentum is directly proportional to its energy. Momentum is crucial for understanding how massless particles, such as photons, interact with other particles and fields in physics.
Photons are known to be chargeless massless... However, since they travell with reletivistic velocity, they gain mass.
Photons do not have an age in the way we think of living organisms aging. They are massless particles that travel at the speed of light and are fundamental to the electromagnetic force, existing independent of time.
There are three known massless particles. Gauge bosons, gluons, and photons.
No, all photons have the same mass. Photons are massless (i.e. zero). All the energy in a photon is in its momentum, but increasing its momentum does not change it speed which is always "the speed of light". All massless particles always move at the speed of light.
The trick behind this is that light is photons, which are massless.
This is a much more complicated question than can be answered with a simple True or False.
