Question:

What is the slope of the graph drawn between frequency of incident light and stopping potential for a given surface?

Options:

$h$

$he^{-1}$

$eh$

$e$

Correct Answer:

$he^{-1}$

Explanation:

$ eV_s = h\nu - \phi$

$ V_s = \frac{h}{e} \nu - \frac{\phi}{e}$

slope is he-1

The correct answer is Option (2) → $he^{-1}$
