U3 6th Grade Waves Study Guide

Front

What is a longitudinal wave?

Back

A type of wave in which the particles of the medium move parallel to the direction of the wave's travel.

Front

What is compression in a longitudinal wave?

Back

The region in a longitudinal wave where particles are closest together.

Front

What is rarefaction in a longitudinal wave?

Back

The region in a longitudinal wave where particles are spread apart.

Front

What is wavelength?

Back

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

Front

What happens to frequency as wavelength decreases?

Back

Frequency increases.

Front

What happens to frequency as wavelength increases?

Back

Frequency decreases.

Front

What is frequency?

Back

The number of waves that pass a point in one second, measured in Hertz (Hz).

Front

How are frequency and wavelength related?

Back

They are inversely related; as one increases, the other decreases.

Front

What is amplitude?

Back

The maximum distance that the particles of a medium move from their rest position in a wave.

Front

What is the difference between wave speed and wave frequency?

Back

Wave speed is how fast the wave travels through a medium, while frequency is how many waves pass a point in a given time.
