Photoelectric Experiment: Intensity, Stopping Potential & Graphs

In photoelectric effect experiment, if the frequency of incident radiation ( $v$ ) is increased, keeping all other factors constant, the stopping potential, ( $v > v_0$ ) ( $v_0$ = threshold frequency)

Show answer and solution

Answer: (c)

$eV_0 = h\nu - \phi \Rightarrow V_0 = \dfrac{h}{e}\nu - \dfrac{\phi}{e}$ .
$V_0$ increases linearly as $\nu$ increases.
So the answer is (c) increases.
