In photoelectric effect, the photocurrent
In photoelectric effect, the photocurrent
- A. depends both on intensity and frequency of the incident light.
- B. does not depend on the frequency of incident light but depends on the intensity of the incident light.
- C. decreases with increase in frequency of incident light.
- D. increases with increase in frequency of incident light.
Step-by-step solution
In the photoelectric effect, the photocurrent (saturation current) is proportional to the intensity of incident light for a fixed frequency above the threshold. It is independent of frequency as long as the frequency is sufficient to cause emission. Thus, option B is correct.
