12.) Light is incident on a photoelectric apparatus made with sodium plates. The distance between the plates is d = 10cm and the stopping voltage is 10V. If I cut the frequency of light in half (but leave the decelerating voltage set to 10V), how far (between the plates) do the electrons make it before turning around? The work function of sodium is = 2.46eV.
