How will the photoelectric current change on decreasing the wavelength of incident radiation for a given photo-sensitive material?

In a photoelectric experiment the relation between applied potential difference between cathode and anode V and the photoelectric current cathode and anode V and the photoelectric current l and was found to be shown in graph below. If planck's constant h=6.6xx10^(-34) Js, the frequency of incident radiation would e nearly (in s^(-1) )
