B) be exactly parallel
C) travel equal distances
D) come originally from the same source
E) be composed of a broad band of frequencies

Question

Quizplus · Accepted Answer

In a Young's experiment, coherence between the two beams is crucial for producing a stable interference pattern. This coherence is best achieved when the beams originate from the same source, as they will have a constant phase relationship. The other options, while potentially affecting the quality or visibility of the interference pattern, are not essential requirements.
