![](https://qIf the intensity of incident light is increased for a photosensitive surface while frequency remains above thrAccording to the notes and the graph, how does stopping potential change when the intensity of incident light The graph of stopping potential $V_0$ versus frequency $\nu$ is shown in the figure. From this graph, which stUsing the graph shown, what does the intercept on the frequency axis represent in the $K_{\max}$ versus $\nu$ Einstein's photoelectric equation is best written as
