Question

When two waves in the same medium hit each other, the resulting displacement of the medium is when two waves in the same medium hit each other, the resulting displacement of the medium is always larger than the displacement due to either wave acting alone. always smaller than the displacement due to either wave acting alone. either larger or smaller than the displacement of either wave acting alone, depending on the signs of the displacements of the two waves?

When two waves in the same medium hit each other, the resulting displacement of the medium is

It is the sum of the displacements of each wave.

This is called the Principle of Superstition. It is that when two waves hit each other, the resulting displacement is the sum of the displacements of the two waves.
