The graph between the stopping potential $(V_{0})$ and wave number $(1/ λ)$ is as shown in the figure. $ϕ$ is the work function, then

Answer:

A, C

Solution:

$V_{0} = \frac{h c}{e} \frac{1}{λ} - \frac{ϕ}{e}$

Horizontal intercepts are proportional to work functions Their plotted ratio is 1 : 2 : 4 The common slope is

$tan θ = \frac{h c}{e}$

giving A,C
