Photons of energy of $6 eV$ are incident on a metal surface whose work function is $4 eV .$ The minimum kinetic energy of the emitted photoelectrons is

Options:

Answer:

Solution:

$\frac{1}{2} m v^{2} = h f - ϕ_{0} = h f - h f_{0}$
The kinetic energy of the emitted photoelectrons is distributed from zero to the maximum value.
minimum kinetic energy of emitted photoelectron is zero.
