Sound Waves Quiz

Select the option that correctly completes the following sentence. Waves are vibrations that:

• transfer matter, but not energy, from one place to another

• transfer energy, but not matter, from one place to another

• transfer both energy and matter from one place to another

• transform energy into matter

Recall which of the following can travel through a vacuum.

• Water waves

• Sound waves

• Light waves

• Radio waves

Identify how particles move in transverse waves.

• At right angles to the direction of the wave

• In the same direction as the wave

• In random directions

• At 45° to the direction of the wave

Identify how the particles move in longitudinal waves.

• At right angles to the direction of the wave

• At 45° to the direction of the wave

• In the same direction as the wave

• In random directions

Classify sound waves as either longitudinal or traverse.

• Longitudinal

• Transverse

Identify what the amplitude of a sound wave corresponds to.

• Loudness

• Wavelength

• Pitch

• Frequency

A student plays two notes on a trumpet and the second note has a higher pitch. The waves produced by the second note have a:

• lower frequency

• higher frequency

• shorter wavelength

Recall what the unit for frequency, 1 hertz (Hz), is equal to.

• 1 metre per second

• 1 wavelength

• 1 centimetre per second

• 1 wavelength per second

The speed of a sound wave changes from 6,100 m/s to 1,484 m/s and then to 344 m/s as it passes through different materials. Determine which of the following sequences could produce these changes in speed.

• air → water → steel

• steel → water → air

• steel → air → water

• water → steel → air
