Back

Quiet, low pitch.

Front

What is the unit for measuring frequency?

Back

Hertz.

Front

What is amplitude in relation to sound waves?

Back

Amplitude refers to the height of the wave, which determines the loudness of the sound.

Front

What is the relationship between frequency and pitch?

Back

Higher frequency results in a higher pitch, while lower frequency results in a lower pitch.

Front

What is a transverse wave?

Back

A wave in which the motion of the medium is perpendicular to the direction of the wave.

Front

What is a compression in a wave?

Back

A region in a longitudinal wave where the particles are closest together.

Front

What is reflection in terms of sound waves?

Back

Reflection occurs when sound waves bounce off a surface.
