According to photon theory of light which of the following physical quantities associated with a photon do not/does not change as it collides with an electron in vacuum
View answer and explanation
Correct option: C
Speed only
Option C (Speed only) is correct because the speed of a photon in a vacuum is constant, while energy and momentum change during collision.
