Which of the following is TRUE regarding photoelectric effect from the experimental data?
Select one:
-The maximum KE decreases with increasing light frequency
-No electrons are emitted if incident light is below cutoff frequency
-The maximum KE of photoelectrons depends on light intensity.
- Photoelectrons require more time to absorb the incident radiation.​

Answer:

Experiments showed that increasing the light frequency increased the kinetic energy of the photoelectrons, and increasing the light amplitude increased the current.

Explanation:

The photocurrent increases linearly with the intensity of the incident light but is independent of its frequency. The stopping potential increases linearly with the frequency of the incident light but is independent of its intensity.
