Question

According to Einstein’s photoelectric equation, the plot of the kinetic energy of the emitted photoelectrons from a metal versus the frequency of the incident radiation gives a straight line whose slope

TestHub · Accepted Answer

According to Einstein’s equation,

Kinetic energy = $h f - ϕ$ where kinetic energy and f (frequency) are variables, compare it with equation,
$y = m x + c$

slope of line = $h$ ( $h$ is Planck’s constant.)

Hence the slope is same for all metals and independent of the intensity of radiation.
