Light of wavelength 0.6mum from a sodium...

Light of wavelength `0.6mum` from a sodium lamp falls on a photocell and causes the emission of photoelectrons for which the stopping potential is 0.5V. With light of wavelength `0.4mum` from a murcury vapor lamp, the stopping potential is `1.5V`. Then, the work function [in electron volts] of the photocell surface is
