Following graph shown the variation of stopping potential corresponding to the frequency of incident radiation (v)(v) for a given metal. The correct variation is shown in graph [ v0=v_0= threshold frequency] Following graph shown the variation of stopping potential corresponding to the frequency of incident radiation (v) for

Options

  1. A(C)
  2. B(B)
  3. C(A)
  4. D(D)

Correct answer

C. (A)

Step-by-step solution

Concept: Stopping potential VV is related to the maximum kinetic energy Kmax⁡K_{\max } of the photoelectrons, via Einstien's photo-electric effect relation: eV=Kmax⁡=hv−hv0e V=K_{\max }=h v-h v_0 Therefore, V=(he)v−(he)v0V=\left(\frac{h}{e}\right) v-\left(\frac{h}{e}\right) v_0 Therefore, VV vs vv is straighline with positive slope and at v=v0v=v_0 the stopping potential is zero.
