Sound Waves Test Review

Front

In which medium do sound waves travel the fastest?

Back

Sound waves travel fastest in solids.

Front

What effect does increasing the frequency of a sound wave have?

Back

Increasing the frequency of a sound wave makes it higher in pitch.

Front

What causes age-related hearing loss?

Back

Age-related hearing loss is caused by the deterioration of hair cells at the base of the cochlea.

Front

Which wave is described as having a very high sound, such as a dog whistle?

Back

Wave D is described as having a very high sound, like a dog whistle.

Front

What is the amplitude of a wave?

Back

The amplitude of a wave is the height of the wave, which in this case is 4.

Front

What is a sound wave?

Back

A sound wave is a type of mechanical wave that travels through a medium (solid, liquid, or gas) due to the vibration of particles.

Front

What is frequency in relation to sound waves?

Back

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

Front

What is the relationship between wavelength and frequency?

Back

Wavelength and frequency are inversely related; as frequency increases, wavelength decreases.

Front

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

Back

The speed of sound in air at room temperature is approximately 343 meters per second.

Front

What is an echo?

Back

An echo is a reflection of sound that arrives at the listener after a delay.
