Question

The photoelectric current can be increased by

• A. increasing frequency
• B. increasing intensity
• C. decreasing intensity
• D. decreasing wavelength

Answer 1

Answer: (B)

increasing intensity

Answer 2

Current in the photoelectric effect is directly proportional to the intensity of the incident light. So,to increase current we have to increase intensity of the light. Current is independent of frequency and wavelength of the incident light.
