to produce hollows at the given instant.Half a period later both sources are producing crests at these samepoints, which are therefore points of great disturbance. At pointssuch as P, Q, R, and S a crest from one source reaches the point atthe same instant as a hollow from the other source. The… … Fig. 648. -Diagram for interference betweentwo sets of ripples. INTERFERENCE 707 The result is that at some points the waves from the two sourcesreinforce each other and at others destroy each other, so that atsome points the disturbance is greater than that due to one setalone, while at other…
