How will the stopping potential change,if frequency of radiation incident on a metal, surface is increased ?

In photo electric effect, why should the photoelectric current increase as the intensity of monochromatic radiation incident on a photosensitive surface is increased? Explain .

Following graphs show the variation of stopping potential corresponding to the frequency of incident radiation (F) for a given metal. The correct variation is shown in graph (V_0=" Threshold frequency")

When light of wavelength lambda is incident on photosensitive surface, the stopping potential is V. When light of wavelength 3lambda is incident on same surface, the stopping potential is V/6 Thereshould wave length for the surface is

Increase in the frequency of the incident radiations increases the

When monochromatic light of wavelength lambda is incident on a metallic surface the stopping potential for photoelectric current is 3V_(0) when same surface is illuminated with light of waelength 2lambda the stopping potential is V_(0) The threshold wavelength for this surface when photoelectric effect takes place is

The slope of frequency of incident light and stopping potential for a given surface will be
