1. In the photoelectric effect, the number of photoelectrons emitted per second is directly proportional to the?

Velocity of the incident light beam

Work function of the photocathode material

Frequency of the incident light

Intensity of the incident light

A more intense light beam delivers more photons per second, ejecting proportionally more electrons — while each electron’s individual energy depends on frequency, not intensity.
