Photoelectric effect and study of photoelectric effect

The graph between 1λand stopping potential (V) of three metals having work functions ϕ1,ϕ2 and ϕ3 in an experiment of photo-electric effect is plotted as shown in the figure. Which of the following statement(s) is/are correct? [Here λ is the wavelength of the incident ray].


eV=hcλϕV=hcϕe=hce1λϕe  Slope =tanθ=hceϕ=hcλϕ1:ϕ2:ϕ3=1λ1:1λ2:1λ3=1:2:4
