Sound Waves Test

Front

What describes the loudness of sound?

Back

Amplitude

Front

In what type of wave does the medium move perpendicular to the movement of the wave?

Back

Transverse

Front

Transverse waves are characterized by what type of motion?

Back

Perpendicular motion of the medium.

Front

What are the parts of longitudinal waves where particles are close together called?

Back

Compressions

Front

What type of wave does sound travel in?

Back

Longitudinal waves.

Front

What is the relationship between amplitude and loudness?

Back

Higher amplitude results in louder sound.

Front

What is the definition of frequency in sound waves?

Back

The number of cycles of a wave that occur in one second.

Front

What is the unit of measurement for frequency?

Back

Hertz (Hz).

Front

What is wavelength in the context of sound waves?

Back

The distance between two consecutive points in phase on a wave.

Front

What is the relationship between wavelength and frequency?

Back

They are inversely related; as frequency increases, wavelength decreases.
