Detailed explanation-1: -A photon is a tiny particle that comprises waves of electromagnetic radiation. As shown by Maxwell, photons are just electric fields traveling through space. Photons have no charge, no resting mass, and travel at the speed of light.

Detailed explanation-2: -Beta rays are emitted by radioactive elements and are not part of the electromagnetic spectrum.

Detailed explanation-3: -A photon (from Ancient Greek , (phôs, phōtós) ‘light’) is an elementary particle that is a quantum of the electromagnetic field, including electromagnetic radiation such as light and radio waves, and the force carrier for the electromagnetic force.

Detailed explanation-4: -Light is a form of electromagnetic radiation and a non-mechanical wave. It does not require a material as a medium for propagation. Hence, it can travel through space.
