WebThus, higher is the value of the stopping potential V 0 , lower will be the value of the work function h ν 0 and vice versa. From the graph, it can be seen that for given value of frequency ν, the stopping potential of A is higher than the stopping potential of B. Hence, the work function of A is lower than the work function of B. WebApr 10, 2024 · Energy versus frequency graph. What is Stopping Potential? Stopping potential, or cut-off potential, is defined as the required potential for stopping the removal of an electron from a metal surface when the incident light energy is greater than the work potential of the metal on which the incident light is focused. The work function and ...
