Question

Monochromatic light with a frequency well above the cutoff frequency is incident on the emitter in a photoelectirc effect apparatus. The frequency of the light is then doubled while the intensity is kept constant. How does this effect the photoelectric current?

• A. The photoelectric current will increase
• B. The photoelectric current will decrease
• C. The photoelectric current will remain the same
• D. None of these

Answer 1

The correct option is C The photoelectric current will remain the same

{C} The current will remain same as current is proportional to intensity and independent of frequency.
