Waves and Sound

Front

What is the relationship between pitch and sound waves?

Back

The pitch of a sound is most closely related to the frequency of the sound waves.

Front

What type of waves are sound waves?

Back

Sound waves are longitudinal waves.

Front

What are waves that require a medium called?

Back

Waves that require a medium are called mechanical waves.

Front

What type of waves have vibrations that move perpendicular to the direction of the wave?

Back

Waves that have vibrations that move perpendicular to the direction of the wave are called Transverse Waves.

Front

How is the loudness of a sound related to the wave?

Back

The loudness of a sound is related to the amplitude of the wave.

Front

Define frequency in the context of sound waves.

Back

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

Front

What is amplitude in sound waves?

Back

Amplitude is the maximum displacement of points on a wave from the rest position, related to the loudness of the sound.

Front

What is the difference between longitudinal and transverse waves?

Back

In longitudinal waves, the vibrations move parallel to the direction of the wave, while in transverse waves, the vibrations move perpendicular to the direction of the wave.

Front

Give an example of a mechanical wave.

Back

Sound waves are an example of mechanical waves.

Front

What is a medium in the context of waves?

Back

A medium is the substance through which a wave travels, such as air, water, or solid materials.
