Question:medium

In a photoelectric experiment, the slope of the graph drawn between stopping potential along y-axis and frequency of incident radiation along x-axis is (Planck's constant = $6.6\times 10^{-34}$ Js)

Show Hint

The slope of the graph of stopping potential ($V_s$) versus incident frequency ($\nu$) in the photoelectric effect experiment is a universal constant equal to $h/e$. This is a key result that allows for the experimental determination of Planck's constant.
