Front

What is a crest in a wave?

Back

The highest point of a wave.

Front

What is a trough in a wave?

Back

The lowest point of a wave.

Front

What type of wave is characterized by particle movement parallel to the direction of wave travel?

Back

Longitudinal wave.

Front

What type of wave is characterized by particle movement perpendicular to the direction of wave travel?

Back

Transverse wave.

Front

What is wavelength?

Back

The distance between two consecutive crests or troughs in a wave.

Front

What is frequency?

Back

The number of waves that pass a point in a certain amount of time, usually measured in Hertz (Hz).

Front

What is amplitude?

Back

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

Front

What happens to the frequency of a wave if the wavelength increases?

Back

The frequency decreases.

Front

What is the relationship between wavelength and frequency?

Back

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

Front

What does it mean for an object to reflect light?

Back

It means that the object bounces back the light that hits it.
