The photon does have mass. You can easily solve for it.
Energy of a photon is ( Planck's konstant times frequency).
But kinetic energy of any moving object is also ( 1/2 m V2 ).
For a photon, 'V' is 'c', so ( h f ) = (1/2 m c2) , and [ m = ( 2 x Planck's konstant x frequency) / c2 ] .
Or, what is equivalent, [ m = ( 2 x Planck's konstant ) / (wavelength x c) ] .
So, there's the mass of your photon, while it's moving at the speed of light ... which it always is.
What it doesn't have is rest mass ... mass that it would have if it were just laying there on the floor.
It can't have rest mass, because any rest mass becomes infinite when the object moves
at the speed of light.
Yes, a photon is an elementary particle.
The photon IS the particle in this case. It isn't known to be made up of any smaller particles. The electric charge of a photon is zero.
A photon is a massless elementary particle that does not have rest mass, while an inertial particle typically refers to a particle with mass that obeys Newton's laws of motion. Photons always travel at the speed of light in a vacuum, whereas inertial particles can have a range of velocities depending on their energy.
A subatomic particle are smaller particles composing nucleons and atoms. The two types of subatomic particle are elementary, they are not made of other particles and composite. A photon is an elementary type of subatomic particle.
Sounds like you are describing a photon.
A photon is an Electrically neutral particle
All nuclear decay has some kind of particle or particles associated with it. Even the metastable decay of 4399Tcm, a gamma at 142.7 Kev, is considered to be a particle emission, because a gamma is a photon, and a photon is an elementary particle, per our understanding of modern quantum mechanics and particle physics, even though it has no mass at rest state.
No, the word 'photon' is a noun, a word for a elementary particle of light and other electromagnetic radiation; a word for a thing.A pronoun is a word that takes the place of a noun in a sentence. The pronoun that takes the place of the noun 'photon' is it.
Photon
No. A photon is a particle of light. It is massless.
A proton can be written as p, p+, or by its quantum numbers: 1/2(1/2)+, corresponding to spin(isospin)parity.
The particle that carries radiant energy is the photon. Photons are elementary particles that travel at the speed of light, carrying energy in the form of electromagnetic radiation. They are responsible for phenomena like light, heat, and other forms of radiant energy.
