Photoelectric Experiment: Intensity, Stopping Potential & Graphs
From the photoelectric effect experiment, following observations are made. Identify which of these are correct.
A. The stopping potential depends only on the work function of the metal.
B. The saturation current increases as the intensity of incident light increases.
C. The maximum kinetic energy of a photo electron depends on the intensity of the incident light. D. Photoelectric effect can be explained using wave theory of light.
Choose the correct answer from the options given below:
Show answer and solution
Answer: (d)
- A false: depends on frequency as well as work function.
- B true: saturation current intensity.
- C false: is independent of intensity. D false: wave theory cannot explain threshold frequency or instant emission.
- So the answer is (d) B only.
