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
    $eV_1(f_1 - f_0)$
✓

Answer

Correct option: C.
$h (f_1 - f_0)$
c
