Answer 2

Answer:

The correct statements are 2) A and B and 3) B and C.

Explanation:

- Statement A: "A photon exists only in motion." This statement is incorrect. Photons can exist at rest or in motion. According to the theory of relativity, a photon always moves at the speed of light, but it can exist at rest in a reference frame moving at the speed of light..

- Statement B: "A photon is a quantum of the electromagnetic field." This statement is correct. Photons are indeed quanta of the electromagnetic field. They are the force carriers for the electromagnetic force and are responsible for electromagnetic interactions..

- Statement C: "The speed of a photon is always equal to the speed of light." This statement is correct. According to the theory of relativity, the speed of a photon in a vacuum is always equal to the speed of light, denoted by 'c'. This is a fundamental principle of modern physics..

Therefore, the correct statements are 2) A and B and 3) B and C.
