Photoelectric Experiment: Intensity, Stopping Potential & Graphs
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 incident radiation. E. Max. K.E of the photoelectrons is independent of the frequency of the incident light. Choose the correct answer from the options given below:
Show answer and solution
Answer: (d)
- A true: photocurrent intensity.
- B false and C true: depends on frequency, not intensity.
- D false: there is a threshold frequency, not a threshold intensity. E false (contradicts C).
- So the answer is (d) A and C only.
