Einstein Equation

Question

Maximum kinetic energy of emitted electron is given by:

RankGuru · Accepted Answer

Einstein's Photoelectric Equation is based on the Conservation of Energy:
$	ext{Energy of incident photon} = 	ext{Work Function} + 	ext{Max Kinetic Energy of electron}$
$hf = \Phi + K_{max}$
$hf = hf_0 + K_{max}$
$K_{max} = hf - hf_0 = h(f - f_0)$
where $h$ is Planck's constant, $f$ is incident frequency, and $f_0$ is threshold frequency.
