The number of photoelectrons emitted per unit time depends on $\left(v>v_{0}\right):$
(a) threshold frequency
(b) frequency of the incident radiation
(c) intensity of the incident radiation
(d) density of the metal irradiated

Key Concepts

Photoelectric Effect

The phenomenon where electrons are ejected from a material's surface when it is exposed to electromagnetic radiation (light) of a high enough frequency. This concept explains that the incident photons transfer energy to electrons, allowing them to overcome the binding forces within the metal.

Threshold Frequency

This is the minimum frequency of incident light required to provide enough energy, via a single photon, to eject an electron from a material. It is a fundamental characteristic of the material related to its work function, but it does not influence the number of electrons emitted once the incident light frequency is above this threshold.

Intensity of Incident Radiation

The intensity of light determines the number of photons hitting the surface per unit time. Above the threshold frequency for photoemission, a higher light intensity means more photons are available, leading to a greater rate of electron emission, which directly correlates to the number of photoelectrons emitted per unit time.

Frequency of Incident Radiation

While the frequency of the incident photons, provided it exceeds the threshold frequency, does not affect the number of electrons emitted, it does determine the kinetic energy of the emitted electrons. Once the threshold condition is met, variations in frequency change the excess energy given to each emitted electron rather than the emission rate.
