Front

What happens to the particles of a medium when a transverse wave passes through it?

Back

Particles move back and forth perpendicular to the wave.

Front

How many total wavelengths are represented from point X to point Y if there are 3 wavelengths?

Front

What is a substance that carries sound waves called?

A medium.

Front

What is an echo?

Back

A sound wave that has been reflected.

Front

What is the speed of sound in air at room temperature?

Back

Approximately 343 meters per second.

Front

What is amplitude in relation to sound waves?

Back

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

Front

What is the relationship between frequency and pitch?

Back

Higher frequency means higher pitch, while lower frequency means lower pitch.

Front

What is the unit of frequency?

Back

Hertz (Hz).

Front

What is the difference between a transverse wave and a longitudinal wave?

Back

In a transverse wave, particles move perpendicular to the wave direction; in a longitudinal wave, particles move parallel to the wave direction.
