Question

question 5.1.12 waves a and b are expected to interfere. constructively constructively destructively

Explanation:

Step1: Recall wave - interference concept

Constructive interference occurs when waves are in - phase (crest meets crest and trough meets trough), and destructive interference occurs when waves are out - of - phase (crest meets trough).

Step2: Analyze waves A and B

Waves A and B have the same phase (crests and troughs are aligned), so they will interfere constructively.

Answer:

constructively
