The freqeuncy(v) of incident radiation is greqter than threshold freqeucy `(v_0)` in a photocell.How will the stopping potential vary ,if frequency(v) is increased,keeping other factors constant?

If the intensity of incident radiations in a photocell is increased, how does the stopping potential vary?

Sketch a graphs showing the variation of stopping potential with frequency of incident radiations for two photosensitive materials A and B having threshold frequencies v_0>v_0' respectively? Which of the two metals A or B has higher work function?

Slope of V_(0) vs v curve is (where V_(0) = Stopping potential, v=subjected freqency)

Write Einstein's photoelectrical equation in terms of the stopping potential and the threshold frequency for a given photosensitive material. Draw a plot showing the variation of stopping potential vs the frequency of incident radiation.

Sketch a graphs showing the variation of stopping potential with frequency of incident radiations for two photosensitive materials A and B having threshold frequencies v_0>v_0' respectively? What does the value of the intercept of graph'A' on the potential axis represent?

Photoelectric effect When light of sufficiently small wavelength is incident on a metal cathode, it may emit electsons called photoelectrons. This is called photoelectric effect. Above threshold frequency, the stopping potential and hence the energy of the photoelectrons is directly proportional to the frequency. In the given figure, we see the variation of stopping potential with the frquency of incident radiation for three metals A, B and C Which metal has the largest threshold wavelength?
