Given below are two statements : Given below are two statements : Statement I : Figure shows the variation of stopping potential with frequency (v) for Statement I : Figure shows the variation of stopping potential with frequency (v)(v) for the two photosensitive materials M1\mathrm{M}_1 and M2\mathrm{M}_2. The slope gives value of he\frac{\mathrm{h}}{\mathrm{e}}, where h\mathrm{h} is Planck's constant, e\mathrm{e} is the charge of electron. Statement II : M2\mathrm{M}_2 will emit photoelectrons of greater kinetic energy for the incident radiation having same frequency. In the light of the above statements, choose the most appropriate answer from the options given below.

Options

  1. ABoth Statement I and Statement II are correct
  2. BStatement I is incorrect but Statement II is correct
  3. CBoth Statement I and Statement II are incorrect
  4. DStatement I is correct and Statement II is incorrect

Correct answer

D. Statement I is correct and Statement II is incorrect

Step-by-step solution

eV0=hv−ϕV0=hev−ϕe\begin{aligned} & \mathrm{eV}_0=\mathrm{hv}-\phi \\ & \mathrm{V}_0=\frac{\mathrm{h}}{\mathrm{e}} \mathrm{v}-\frac{\phi}{\mathrm{e}} \end{aligned}\mathrm{M}_2$ material has higher work function, so statement-(II) is incorrect.
