Question

define constructive interference and destructive interference​

Answer 1

Answer:

Constructive interference occurs when the maxima of two waves add together (the two waves are in phase), so that the amplitude of the resulting wave is equal to the sum of the individual amplitudes.

Destructive interference occurs when waves come together in such a way that they completely cancel each other out. When two waves interfere destructively, they must have the same amplitude in opposite directions.

Answer 2

Answer:

Constructive interference : When the crests or troughs of two interfering waves meet, their amplitudes add together. This principle is known as constructive interference.

Destructive interference: Destructive interference occurs when the maxima of two waves are 180 degrees out of phase: a positive displacement of one wave is cancelled exactly by a negative displacement of the other wave. The amplitude of the resulting wave is zero.
