NEET Physics Photoelectric Effect Multiple Correct Question
In photoelectric 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 varies linearly with the frequency of incident light.
D. The emission of photoelectrons require a minimum threshold intensity of incident radiation.
E. Max. K.E of the photoelectrons is independent of the frequency of the incident light.
F. For a frequency ν of incident radiation, lower than the cut-off frequency ν₀, no photoelectric emission is possible even if the intensity is large.
A and C only
A, C & F only
B and C only
A and D only
Correct Answer
Detailed Explanation
The photoelectric effect shows that the photocurrent is proportional to the intensity, but the maximum kinetic energy depends on the frequency, not the intensity. A threshold frequency is required for emission.
