MCQ
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 reaching the collector is determined for different frequencies $f$ of the incident illumination. The graph obtained is shown. The maximum kinetic energy of the electrons emitted at frequency $f_1$ is


- A$hf_1$
- B$\frac{{{V_1}}}{{({f_1} - {f_0})}}$
- ✓$h (f_1 - f_0)$
- D$eV_1(f_1 - f_0)$
