Light of frequency $v$ falls on a metal whose work function is $hv_0$. Choose the most appropriate condition from the following under which the photoelectric effect will take place:

$v>v_0$

The correct answer is Option (1) → $v>v_0$

For the photoelectric effect to occur, the energy of the incident light must be greater than or equal to the work function.

$hv>hv_0$ [$v_0$ = Threshold frequency]

$⇒v>v_0$
