Question

Explain the concept of photon and write its properties.

Answer 1

Answer:

The photon is a type of elementary particle. It is the quantum of the electromagnetic field including electromagnetic radiation such as light and radio waves, and the force carrier for the electromagnetic force (even when static via virtual particles). The invariant mass of the photon is zero; it always moves at the speed of light in a vacuum. Properties of photon:-

They have zero mass and rest energy. They only exist as moving particles. They are elementary particles despite lacking rest mass. ... They carry energy and momentum which are dependent on the frequency. They can have interactions with other particles such as electrons, such as the Compton effect
