2. American physicists Davisson and Germer did a diffraction experiment in the 1920s to demonstrate the wave-like property of electrons. If d is 0.215 nm for a cubic lattice crystal (see Fig. 1), and the incident beam is perpendicular to the surface of the crystal, (a) and o. find the optical path length difference between ray 1 and ray 2 in terms of d (b) peak would be observed at 0 = 53.13°? |how much voltage has to be applied to a beam of electrons so the diffraction Diffracted rays Incident rays 1 2 1 d Figure 1: Problem 2.
