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.
A photon is an elementary particle, the quantum of light and all other forms of electromagnetic radiation, and the force carrier for the electromagnetic force, even when static via virtual photons. The photon is not on the eye.
A photon is an Electrically neutral particle
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.
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.
When a photon strikes a solar cell it bounces off. In Physics, a photon is an elementary particle, the quantum of the electromagnetic interaction and the basic unit of light and all other forms of electromagnetic radiation.
It isn't clear what you mean by "its" inertial particle. There is no inertial particle associated with the photon.

No. A photon is a particle of light. It is massless.
Sounds like you are describing a photon.
A photon.
UV means ultraviolet, and a photon is a particle of light.
