Question

What is the photoelectric equation?

Answer 1

Photoelectric equation:

1. To emit an electron from the metal surface, the photon requires energy equal to the sum of electron kinetic energy and electron removal energy.
2. The photoelectric equation is $\mathrm{E}=\mathrm{h\nu }-\mathrm{W}$. Here, $\mathrm{E}$ is the photoelectron's kinetic energy, $\mathrm{h}$ is the Planck constant, $\mathrm{v}$ is the frequency associated with the radiation quantum, and $\mathrm{W}$ is a work function.
