Using the principle of superposition, explain the relationship between destructive interference and path difference. Include a diagram with your answer. The figure below shows two sources (S, and S2) that emit waves. The waves are identical () = 1.0 m) and are emitted in phase. A detector (P) is located 6.0 m away from S1. Initially, the sources are separated by 1.0 m; however, S2 is systematically moved closer to the detector in increments of 0.5 m. Li L2 S2 P + +
