1. Double-slit experiment Use this information to answer Question 1-2: Following the standard analysis of double slit experiment (see, for example, https://en.wikipedia.org/wiki/Double-slit experiment), the interference pattern on the screen is described by 12612 a cos? () = [1 + cos (278) where d = slit separation, D = distance between slit and screen, z = position on the screen and ) = wavelength of electron. We conduct the double slit experiment using an electron beam. Find the fringe spacing (distance between two adjacent bright spots) for the case where d = 0.5 nm, D = 1 m and the incident electron energy of 1 MeV. Give the answer in unit of m. Answers within 5% error will be considered correct.
