Answer
The correct answer is:
(e) none of the above
Work Step by Step
We can write an equation for the maximum kinetic energy of an electron in the experiment:
$K_{max} = \frac{hc}{\lambda}-\phi$
As the intensity of the light increases, the number of photons increases, which results in a greater number of electrons being ejected from the metal.
However, the work function $\phi$ does not change since $\phi$ is a characteristic of the material.
Since $\phi$ does not change and $\lambda$ does not change, $K_{max}$ does not change. Since the stopping potential is proportional to $K_{max}$, the stopping potential does not change.
The correct answer is:
(e) none of the above
