Draw a graph between stopping potential and the frequency of two metals A and B having threshold frequencies `v_0 and 2v_0` .

Explain the term stopping potential and threshold frequency.

The graph between the stopping potential V_(0) and frequency v for two different metal plates P and Q are shown in the figure. Which of the metals has greater threshold wavelength and work function.

In the study of a photoelectric effect the graph between the stopping potential V and frequency v of the incident radiation on two different metals P and Q is shown in fig. (i) which one of two metals have higher threshold frequency (ii) Determine the work function of the metal which has greater value (iii) Find the maximum kinetic energy of electron emitted by light of frequency 8xx10^(14) Hz for this metal.

Photons of frequency v fall on a metal surface for which the thershold frequency is v_(0)(vge v_(0)) . Then,

Sketch the graphs, showing the variation of stopping potential V_s with frequency v of the incident radiations for two photosensitive materials A and B having threshold frequencies v_0gtv'_0 respectively. (i) which of the two metals A or B has higher work function? (ii) What information do you get from the slope of the graphs? (iii) What does the value of the intercept of graph A on the potential axis represent?

The graph shows variation of stopping potential V_(0) versus frequency of incident radiation v for two photosensitive metals A and B . Which of two metals has higher threshold frequency and why?

Relation between the stopping potential V_0 of a metal and the maximum velocity of the photoelectrons is
