What do you mean by photoelectric effect?

In a photoelectric experiment, the relation between the applied potential difference $V$ and the photoelectric current $I$ was found to be as shown in the graph below. If the work function of the cathode plate is $28.8 \mathrm{eV}$ and $h=6.6\times {10}^{-34} \mathrm{J} \mathrm{s},$ the frequency of incident radiation would be nearly ( in $\mathrm{Hz}$)
