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

Asked in JEE Main 16th March 1st Shift 2021 · What the stopping potential depends on

Answer: (2) frequency

Step-by-step solution

eV₀=h u-φ.

The only property of the radiation on the right-hand side is its frequency.

Amplitude, phase and intensity control the number of photons arriving, never the energy of one.

Why the other options are wrong
