Waves Characteristics

Which is true of a mechanical wave?

• It must have a medium

• It must travel in empty space.

• It can travel in a vacuum (no matter).

• Both sound and light are examples.

What is the amplitude of a wave?

• The distance from crest to crest or trough to trough

• The height or depth of a wave.

• The number of waves produced in a given amount of time.

• The speed at which a wave travels.

A transverse wave can be created in a Slinky^® by moving it

• side to side.

• in a circular motion.

• together and apart.

• up and down.

When on a flat surface, giving the Slinky^® a push or pulse will create a disturbance

• in the opposite direction of the wave motion.

• parallel to the wave motion.

• in a circle.

• perpendicular to the wave motion.
