In photo electric effect A. The photocurrent is proportional to the intensity of the incident radiation. B. Maximum kinetic energy with which photoelectrons are emitted depends on the intensity of incident light. C. Max. K.E with which photoelectrons are emitted depends on the frequency of incident light. D. The emission of photoelectrons require a minimum threshold intensity of the incident radiation. E. Max. K.E of the photoelectrons is independent of the frequency of incident light. Choose the correct answer from the options given below: (1) A and B only (2) A and E only (3) A and C only (4) B and C only

1. A and B only
2. A and E only
3. A and C only
4. B and C only

Correct answer: A and C only

Solution

The correct option is A and C because the photocurrent is indeed proportional to the intensity of the incident radiation, reflecting the number of emitted photoelectrons, while the maximum kinetic energy of the emitted photoelectrons is determined by the frequency of the incident light, not its intensity.
