Radiation of frequency $2 v_0$ is incident on a metal with threshold frequency $v_0$. The correct statement of the following is _________.

Fill in the blank with the correct answer from the options given below.

Maximum kinetic energy of photoelectrons emitted can be $h v_0$

The correct answer is Option (3) → Maximum kinetic energy of photoelectrons emitted can be $h v_0$

In the photoelectric effect, the maximum kinetic energy of emitted photoelectron is,

$K_{max}=h(v-v_0)$

$v_0$ = Threshold frequency

$v$ = frequency of incident light

$K_{max} =h(2v_0-v_0)=hv_0$
