The graph shows variation of stopping potential $\displaystyle V_{\mathrm{o}}$ with the frequency $\displaystyle v$ of the incident radiation for three photosensitive metals $\displaystyle X_1, X_2$ and $\displaystyle X_3$. Which metal will give out electrons with greater kinetic energy, for the same wavelength of incident radiation?
