Which of the following statements are correct?

A. Photoelectric current depends on the intensity of light.
B. The stopping potential is directly related to the maximum kinetic energy of electrons emitted which is dependent on the intensity of incident radiation.
C. Photoelectric emission from a metal surface occurs due to absorption of a photon by an electron.
D. Photoelectric effect follows the law of conservation of energy.

Choose the correct answer from the options given below:

A, C and D only

The correct answer is Option (3) → A, C and D only

(A) Higher intensity means more photon strike the surface, leading to more emission of more electron and hence a higher current.

(C) The photoelectric effect occurs when a photon is absorbed by an electron, imparting enough energy to eject the electron from the metal surface.

(D) The energy of the incoming photon is used to overcome the work function of a metal, while the remaining energy is being converted to kinetic energy of electron.
