What happens to a piece of driftwood in a lake with waves? 1. It moves in the direction the waves are moving. 2. Cannot be determined 3. It will move up and down as a result of the waves.

The piece of driftwood in a lake with waves will move up and down as a result of the waves. The correct option is 3.

Explanation:

Waves can be defined as disruption that occurs in a medium which is regularly propagated in an organised way. There are two types of mechanical waves and these are the longitudinal wave and the transverse wave. Ocean waves are created as energy passes through the water. The combination of both transverse and longitudinal wave are found in water wave but at different levels. At the surface, transverse waves are seen which is the displacement of particle perpendicular to the direction of wave propagation. Therefore the piece of driftwood in a lake will simply oscillate up and down about its equilibrium position as the wave passes by. I hope this helps, thanks!
