Why photon has no mass?

One of the postulates of the Standard Model is that photon are massless elementary particles. This means that they do not contribute to the mass of matter. Although there are many different theories that explain the origin of the photon’s mass, the Standard Model is still the most accepted theory among physicists.

Why photons have no mass?

The photon is also one of the elementary particles. Mass is an aspect of matter and the strength of matter is represented by the number of elementary particles it contains. Therefore, the heavier an object is, the more the mass it has. In other words, the number of particles in an object determines its mass. A photon is an elementary particle that is emitted as a result of a process of creation and annihilation of matter. It is a particle of light. It has no mass and is therefore referred to

Why photons have zero mass?

As photons are created through the interaction of charged subatomic particles, they are massless. The primary reason for this is that mass is associated with the interaction of energy and matter. If you have two objects, they will attract each other due to their mass. However, the energy that is moving between them is not affected by the sum of their masses, as it is independent of the objects. Likewise, two photons can have the same energy, but they will not attract each other due to their mass

Why photon has no mass in quantum electrodynamics?

As mentioned before, it is because photon is an elementary particle. It is not made up of quarks, electrons and other particles. It is an elementary particle which is created when 2 or more photons collide with each other. This phenomenon is called as spontaneous photon pair creation. In other words, any particle that has electric charge can emit or absorb a photon in its surrounding. A charged particle can absorb or emit a photon due to its electric dipole moment. Now, the question arises that if photon

Why photon has no rest mass?

The answer lies in the fact that mass is not a measure of something tangible. It is a measure of the response of matter to the gravitational force. One can use Newton’s laws to calculate the mass of an object from its motion. But it still remains a concept. If there is no force acting on the object, it will be at rest. And if there is no motion, there is no force acting on it. A photon is an elementary particle that has no size and no volume
