Please read our article on Lenard’s observations to understand this part. … Webb24 dec. 2015 · In the photoelectric experiment, when light, having frequency greater than the threshold frequency, falls on a metal, electrons are emitted. Since electrons emitted are of different energies (I presume it's because they're coming from different energy levels in the lattice of the metal), not all of them are able to reach the anode per second.

The photons of a light beam have a characteristic energy, called photon energy, which is proportional to the frequency of the light. In the photoemission process, when an electron within some material absorbs the energy of a photon and acquires more energy than its binding energy, it is likely to be ejected.
