In photoelectric effect, does the photoelectric current depend on the intensity of incident radiation? Give reasons.

Define the term threshold frequency and stopping potential in relation to phenomenon of photoelectric effect. How is the photoelectric current affected on increasing the intensity of incident radiation and why?

What is photoelectric effect?

Does the thresold frequency depend on intensity of light?

Draw a plot showing the variation of photoelectric current versus the intensity of incident radiation on a given photosensitive surface.

For a given photosensitive material, how does photoelectric current change on decreasing the wavelength of incident radiation?
