PhysicsPhotoelectric Effect

A ray of light with wavelength lambda is incident on three different photoelectric cells numbered 1, 2 and 3. Their threshold wavelengths are lambda_1, lambda_2 and lambda_3 respectively, and the magnitudes of the stopping potentials are V_1, V_2 and V_3 respectively. Given lambda_1 < lambda, lambda_2 > lambda and lambda_3 >> lambda, the correct option is:
