photoelectric current hard

Question

Increasing light intensity (above threshold) primarily increases:

RankGuru · Accepted Answer

Intensity of light corresponds to the number of photons hitting a unit area per second ($N$).
- Each photon (above threshold) liberates exactly one electron.
- Therefore, higher intensity leads to a higher **Photoelectric Current** ($I$, number of electrons per second).
- Crucially, intensity has **no effect** on the maximum kinetic energy of the electrons; that is determined solely by the photon's frequency ($f$).
