In an experiment on photoelectric effect, the following graphs were obtained between the photoelectric current 'I' and anode potential V. Name the characterstics of this incident radiation that was kept constant in this experiment.

Sketch a graph between frequency of incident radiations and stopping potential for a given photosensitive material. What information can be obtained from the value of the intercept of potential axis?
