Unit 3 Test Review

Front

What is the medium for a transverse wave created by a metal slinky?

Back

The medium is the material through which the wave travels. In this case, the medium is metal.

Front

What happens to the speed of a wave when it moves from a liquid to a solid?

Back

The speed of the wave will increase.

Front

What happens to the speed of a wave when it moves from a liquid to a gas?

Back

The speed of the wave will decrease.

Front

How can you determine which waves have the same frequency?

Back

Waves have the same frequency if they complete the same number of cycles in a given time period.

Front

What is a complete wave cycle?

Back

A complete wave cycle consists of one full wave crest and one full wave trough.

Front

What is the relationship between wave speed, frequency, and wavelength?

Back

Wave speed = frequency × wavelength.

Front

What is a transverse wave?

Back

A transverse wave is a wave in which the motion of the medium is perpendicular to the direction of the wave's travel.

Front

What is a longitudinal wave?

Back

A longitudinal wave is a wave in which the motion of the medium is parallel to the direction of the wave's travel.

Front

What is frequency in the context of waves?

Back

Frequency is the number of complete wave cycles that pass a point in one second, measured in Hertz (Hz).

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive points that are in phase on a wave, such as crest to crest or trough to trough.
