Question

Which statement below is correct concerning free and/or forced waves?

a. Swell is an example of a free wave that exists only when the generating force
is present.
b. A rock thrown into the water will create free waves that radiate out from the point of impact.
c. Tides are free waves created by the interaction of the moon's and sun's tide producing force.
d. A forced wave runs free of the generating force.

Answer 1

The correct statement concerning free and/or forced waves is option c. Tides are free waves created by the interaction of the moon's and sun's tide producing force.

Step-by-step explanation:

The correct statement concerning free and/or forced waves is option c. Tides are free waves created by the interaction of the moon's and sun's tide producing force.

A free wave is a wave that exists without the presence of a generating force. In the case of tides, the gravitational forces of the moon and the sun create a tidal force that results in the rise and fall of sea levels, creating free waves.

On the other hand, forced waves are waves that require a generating force to exist. For example, a rock thrown into the water will create free waves that radiate out from the point of impact. The generating force in this case is the energy from the rock hitting the water surface.
