Question

In photoelectric effect experiment, the slope of the graph of the stopping potential versus frequency gives the value of ______.

Options

• `h/e`

• h

• `e/h`

• `(hc)/e`

Answer 1

In photoelectric effect experiment, the slope of the graph of the stopping potential versus frequency gives the value of `bbunderline(h/e)`.

Explanation:

eV₀ = hv

⇒ `V_0/v = h/e`
