Lexy says that the diffraction angle is the one labeled R, and Jin says that the diffraction angle is the one labeled S. Which best explains who is correct? Lexy is correct because angle R is between the incident wave, n = 0, and a diffracted wave. Lexy is correct because angle R includes the diffracted wave at n = 1. Jin is correct because angle S is measured from the barrier and includes n = 2, the wave that has the most diffraction. Jin is correct because angle S is between the dimmest order bands, n = 1 and n = 2.
