Write Einstein's photoelectric equation and explain the terms involved.

Q: Write Einstein's photoelectric equation and explain the terms involved.

Einstein's photoelectric equation is given by $ K{\max} = h\nu - \phi0 $ or $ eV0 = h\nu - h\nu0 $. Here, $ K{\max} $ is the maximum kinetic energy of the emitted photoelectrons, $ h\nu $ is the energy of the incident photon, $ h $ is Planck's constant, $ \nu $ is the frequency of incident radiation, $ \phi0 $ is the work function, and $ V0 $ is the stopping potential.
