Photons are easily created and destroyed. An electron moving in a strong magnetic field will generate photons just from its acceleration. Similarly, when a photon of the right wavelength strikes an atom, it disappears and imparts all its energy to kicking the electron into a new energy level.

Each photon has a wavelength and a frequency. The wavelength is defined as the distance between two peaks of the electric field with the same vector. The frequency of a photon is defined as how many wavelengths a photon propagates each second. Unlike an electromagnetic wave, a photon cannot actually be of a color.

Since photons (particles of light) have no mass, they must obey E = pc and therefore get all of their energy from their momentum. But an object with zero energy and zero mass is nothing at all. Therefore, if an object with no mass is to physically exist, it can never be at rest. Such is the case with light.

A photon of light does not accelerate to light speed. Rather, a photon is already traveling at light speed c when it is created. Like water waves, sound waves, and all other waves, light waves are already going at a certain non-zero speed the moment they are created, without needing to be accelerated.

1 Answer. No, we cannot make photons travel at any value other than the speed of light. It is a postulate of the theory of relativity and it works because solutions to the equations of electromagnetism indicate that light/photons must travel at a constant speed regardless of observer.

Science: Can photons travel ‘faster than light’? LIGHT cannot travel faster than it does in a vacuum. The proposed effect, however, is very small indeed: the photons can exceed Einstein’s limit by only one part in 1036.

Tachyons are hypothetical particles that travel faster than light.

A single photon differs from another photon only by its energy. In empty space (vacuum) all photons travel with the same speed or velocity. Photons are slowed down when they pass through different media such as water, glass or even air.

The frequency of the radiation is proportional to its energy and the wavelength of the radiation is inversely proportional to the energy. Red is the lowest energy visible light and violet is the highest. A solid object has color depending on the light it reflects.
