P12 - Mechanical Waves Revision

What does a wave transfer?

• Energy

• Matter

• Nothing

• Force

Which type of wave has areas of compression and rarefaction?

• Transverse

• Longitudinal

• Electromagnetic

• Mechanical

Which of the following are longitudinal waves?

• Water waves

• Sound waves

• Seismic S-waves

• Seismic P-waves

Match the wave type to the motion:

• Oscillations are perpendicular

• Transverse wave

• Can travel through a vacuum

• Water wave

• Oscillations are parallel

• Electromagnetic wave

• Surface oscillations in a medium

• Longitudinal wave

How do we know that water waves do not carry water away from the wave's source?

A student is measuring the wavelength of water waves. They measure the length of 10 waves and then divide their measurement by 10. Why?

What is the amplitude of a wave?

• The maximum displacement of a wave away from the equilibrium position.

• The height of a wave measured from a trough up to a peak.

• The distance between two neighbouring peaks.

• The distance between two neighbouring areas of compression.

• The distance between two neighbouring areas of compression.

What is frequency of a wave, and the correct unit?

• Frequency is the time taken for one wave, in hertz.

• Frequency is the time taken for one wave, in seconds.

• Frequency is the number of waves in a second, in hertz.

• Frequency is the number of waves in a second, in seconds.

When the frequency of a wave increases, the period of the wave also increases.

• True
• False
