Answer:
Constructive interference is when a crest interferes a crest or trough interferes a trough, it results in a larger crest or trough while
Destructive interference is when a crest interferes a trough or a crest interferes a trough, it results in cancellation and it produces a smaller disturbance
In constructive interference the displacement of the waves interfere in same directions. While
In destructive interference the displacement of the waves interfere in opposite directions
In constructive interference the amplitude of the resultant waves at a given position or time is greater than that of either individual waves. While
In destructive interference the amplitude of the resultant waves is less than that of either individual waves.
