(03.03 mc)when two mechanical waves have a displacement in the same direction, and they overlap, what will the resulting wave look like and why?

Answer;

-The resulting wave would have a displacement equal to the sum of the two initial waves.

This property of a wave is called Constructive interference.

Explanation;

-When two mechanical waves have a displacement in the same direction, and they overlap, then the resulting wave would have a higher amplitude or displacement compared to the original waves. This is referred to as constructive interference.

-Constructive interference takes place when two mechanical waves that have positive displacements from the equilibrium position meet and coincide.

-On the other hand, destructive interference takes place when one mechanical wave has a positive displacement and the other a negative displacement meet and coincide.
