Photoelectric Experiment: Intensity, Stopping Potential & Graphs

The stopping potential in the context of photoelectric effect depends on the following property of incident electromagnetic radiation:

Show answer and solution

Answer: (b)

$eV_0 = h\nu - \phi$ .
Of the properties of the radiation, only frequency enters; phase, amplitude and intensity do not.
So the answer is (b) frequency.
