If the frequency of incident radiation (v) is increased, keeping other factors constant, the stopping potential ($v \gt v_0$, threshold frequency)
  1. increases
  2. decreases
  3. remains constant
  4. suddenly becomes zero

Solution

$\mathrm{eV}_{\mathrm{s}}=\mathrm{h} \nu-\mathrm{W}_0$ $\therefore \quad$ If $v$ increases, $\mathrm{V}_{\mathrm{s}}$ will increase.
