Toppr Admin · Accepted Answer

The photoelectric effect related with the incident light frequency $(ν)$ by the following equation:
$E_{k} = e V_{s} = h ν - ϕ$ ,
where $ϕ$ is the work function of the material and $E_{k}$ is the kinetic energy of the photo electron. So the photoelectrons emitted from the surface of sodium metal are of speeds from zero to a certain maximum depending on the incident photon energy.
So, the answer is option (A).
