Photoelectric Experiment: Intensity, Stopping Potential & Graphs

Which one of the four graphs showing lines P, Q, R and S between maximum kinetic energy (E) and intensity of incident radiation (I) is correct?

Show answer and solution

Answer: (a)

$E_{max} = h\nu - \phi$ does not depend on intensity $I$ .
So the E–I graph is a horizontal line above the I-axis, which is line P.
So the answer is (a) P.
