Question

In a photoelectric experiment, the potential difference V that must be maintained between the illuminated surface and the collector so as just to prevent any electron from traching the collector is determined for different frequencies f of the incident illumination. The graph obtained is shown. The maximim kinetic energy of the electrons emitted at frequency $f_{1}$ is
