What is the difference between constructive interference and destructive interference?

In constructive interference, interactions between waves lead to a greater amplitude. This occurs when the peaks of waves coincide. On the other hand, in destructive interference, interactions between waves lead to a smaller amplitude. This happens when the peak of one wave coincides with the trough of another.

It's easier to understand if you try looking up a picture of each kind of interference! :)

Constructive interference is when the waves that meet are in the same direction, which could result in higher peaks. Destructive interference occurs when displacement of the waves that meet are in opposite directions; this could result in lower peaks.
