Question

wnwhat is the difference between a quantum and a photon ?

Answer 1

Dear student,

Photon:

• A photon can be defined as quantum of energy. It is an elementary particle.
• It can be the quantum of the electromagnetic field including electromagnetic radiation such as light,
• The photon has zero rest mass and always moves at the speed of light within a vacuum.

Quantum

• a quantum (plural: quanta) is the minimum amount of any physical entity (physical property) involved in an interaction.
• For example, a photon is a single quantum of light , and can be referred to as a "light quantum", or as a light particle.

Difference :

1. A photon has the properties of both wave like and particle like, but quantum does not.
2. Quantum can be compared to a measure of quantity, but a photon is not about a measure of quantity.
