Front

What kind of wave are sound waves?

Back

Sound waves are longitudinal waves.

Front

True or False: Sound waves are faster than light.

Back

False

Front

What does the amplitude of a wave represent?

Back

The amplitude of a wave represents the maximum displacement of points on a wave, which relates to the energy of the wave.

Front

What produces sound?

Back

Sound is produced by vibrations.

Front

In a mechanical/longitudinal wave, what does B represent?

Back

B represents rarefaction.

Front

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

Back

Approximately 343 meters per second.

Front

What is wavelength in the context of sound waves?

Back

Wavelength is the distance between successive crests or compressions in a wave.

Front

What is frequency in sound waves?

Back

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

Front

How does temperature affect the speed of sound?

Back

The speed of sound increases with an increase in temperature.

Front

What is the relationship between frequency and pitch?

Back

Higher frequency sound waves produce higher pitch sounds.
