A photoelectric material having work function ϕ_0 is illuminated with light of wavelength \lambda(\lambda < {hc/ϕ_0) fastest photoelectron has a de Broglie wavelength \lambda_d.A change in wavelength of the incident light by \Delta\lambda results in a change \Delta\lambda_d in \lambda_d. Then the ratio \frac{\Delta\lambda_d}{\Delta\lambda} is proportional to : [JEE Adv 2017 P2]
