E = hν - Φ
Where:
* E is the kinetic energy of the emitted electron (also known as the photoelectron).
* h is Planck's constant (6.626 x 10⁻³⁴ Js).
* ν is the frequency of the incident light.
* Φ is the work function of the metal, representing the minimum energy required to remove an electron from the metal's surface.
This equation explains the photoelectric effect by stating that the energy of the incident light (hν) is used to overcome the work function (Φ) and provide the kinetic energy (E) to the emitted electron.
