Constructive interference occurs when two waves:
A.Are 180° out of phase
B.Are in phase
C.Have different frequencies
D.Travel in opposite directions
Explanation
Core Concept
Constructive interference occurs when two waves are in phase (their crests and troughs align), causing their amplitudes to add together and produce a larger wave.
