If c is the velocity of light in free space, the correct statements about photon among the following are: A. The energy of a photon is E=h v. B. The velocity of a photon is c. C. The momentum of a photon, p= h c . D. In a photon-electron collision, both total energy and total momentum are conserved. E. Photon possesses positive charge. Choose the correct answer from the options given below:

Quantrex Academy · Accepted Answer

Correct answer: A. A, B, C and D only

(A) If c is the velocity of light so, E=h (Energy of photon) (B) Velocity of photon is equal to velocity of light i.e. c. (C) = h p aligned & p= h \ & p= h c aligned (D) In photon-electron collision both total energy and total momentum are conserved.
