In an experiment on photoelectric effect, a student plots stopping potential $\mathrm{V}_0$ against reciprocal of the wavelength $\lambda$ of the incident light for two different metals $\mathrm{A}$ and $\mathrm{B}$ . These are shown in the figure.
Looking at the graphs, you can most appropriately say that:

Correct answer: D. Students data is not correct

aligned & hc λ -φ=eV_0 & v_0= hc e λ - φ e aligned As the value of (1)/(λ) (increasing and decreasing) is not specified hence we cannot say that which metal has comparatively greater or lesser work function (φ) .
