Photoelectric Experiment: Intensity, Stopping Potential & Graphs

Light of frequency 1.5 times the threshold frequency is incident on photosensitive material. If the frequency is halved and intensity is doubled, the photocurrent becomes

Show answer and solution

Answer: (d)

$\nu = 1.5\nu_0$ ; halved: $\nu' = 0.75\nu_0 < \nu_0$ .
Below threshold no emission, even with double intensity.
So the answer is (d) zero.
