The sources S₁ and S₂ are coherent sources, and the circular arcs represent wave crests. The position that corresponds to a path difference of two wavelengths is A) 1. B) 2. C) 3. D) 4. E) 5.

Question

Quizplus · Accepted Answer

The path difference between sources S₁ and S₂ is equal to the distance between the two sources, which is two wavelengths. Therefore, the position that corresponds to a path difference of two wavelengths is at point D, where the two waves are in phase (crest meets crest) and constructive interference occurs.

The Sources S1 and S2 Are Coherent Sources, and the Circular
