Question

For an experiment of photoelectric effect, a graph between 1/λ and stopping potential (V) of three metals A, B and C whose work functions are φ_A, φ_B & φ_C respectively, is plotted as shown in the figure. Which of the following statement(s) is/are correct? [Here λ is the wavelength of incident light]

φ_A = φ_B = φ_C

θ_A < θ_B < θ_C

θ_A = θ_B = θ_C

φ_A < φ_B < φ_C

$eV = \frac{hc}{λ} - φ$
$\frac{1}{λ} = \frac{eV}{hc} + \frac{φ}{hc}$
