If the frequency of incident radiations is equal to the thresold frequency, what will be the value of stopping potential?

For photoelectric effect in a metal, the figure shows the plot of cut off voltage versus frequency of incident radiations. Calculate (a) the threshold frequency (b) the work function for given metal.

Given instructions same as in chapter 1. Assertion: For photoelectric effect to take place, the frequency of incident of incident radiations should be more than threshold frequency of a given metal Reason: 1/2 mv^2=h(v-v_0) .

What is the unit of frequency ?

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

If high waves of frequency 8.8 xx 10^(14) Hz is incident on a metal surface of thresold frequency 4 xx 10^(14) Hz, then determine the value of stopping potential (cut-off Potential) (Given h=6.6 xx 10^(-34) Js and e = 1.6 xx 10^(-19)C)

Does the thresold frequency depend on intensity of light?

Draw a graph showing the variation of stopping potential with frequency of incident raditions in relation to photoelectric effect. Deduce an expression for the slope of this graph using Einstein's photoelectric equation.
