<p>The graph below shows the variation of stopping potential (<span class="equation">\(V_0\)</span>​) with frequency (&nu;) of incident light for two photo-sensitive metals A and B. Both metals are exposed to monochromatic light under identical conditions. Using the information from the graph, answer the following:</p>

<p>(i) Which metal possesses a smaller threshold wavelength? Justify your answer in terms of the intercept of the&nbsp;<span class="equation">\(V_0 -v\)</span>&nbsp;graph.</p>

<p>(ii) For a given wavelength of incident light, which metal will emit photoelectrons having lower maximum kinetic energy? Support your answer with reasoning.</p>

<p>(iii) If the intensity of incident light on metal A is reduced by increasing the distance of the light source to double its original value, what change, if any, will occur in the stopping potential? Explain your answer.</p>
