Question

What happens when a small stone is dropped on a calm pool of water?

Options

• Waves spread out from the point of impact.

• The wavefront becomes a plane at the point of impact.

• The energy travels parallel to the wavefront.

• Waves spread out from a common tangent.

Answer 1

Dropping a small stone produces waves that spread out from the point of impact. This illustrates how a disturbance moves outwards from its source.
