Question

In a surface wave (such as a water wave), particles __________.

Answer 1

Moves perpendicular and parallel to the direction of wave motion

Answer 2

moves perpendicular to the wave travel

Step-by-step explanation

Water wave is a transverse waves. The particles in this type of a wave moves perpendicular to the wave travel.

This wave is also a mechanical wave. This means it requires a material medium for propagation.

The answer to the question is "moves perpendicular to the wave travel".
