Grade Physics Waves Quiz

What is the definition of amplitude in a wave?

• The time it takes for one complete wave to pass a certain point

• The height of a wave measured from rest to crest

• The number of complete waves that occur in one second

• The distance from one point on a wave to the same point on the next wave

In which type of wave are vibrations at 90° to the direction of energy transfer?

• Light waves

• Sound waves

• Ripples on the surface of water

• Shockwaves

What is the relationship between wave speed, frequency, and wavelength?

• Wave speed = frequency × wavelength

• Wave speed = frequency ÷ wavelength

• Wave speed = frequency + wavelength

• Wave speed = frequency - wavelength

What is the unit of measurement for frequency?

• Hertz (Hz)

• Second (s)

• Metre (m)

• Degree (°)

What is the direction of vibrations in a longitudinal wave?

• Towards the direction of wave travel

• Away from the direction of wave travel

• In the same direction as the wave travel

• 90° to the direction of wave travel

What is the unit of measurement for wavelength?

• Hertz (Hz)

• Second (s)

• Metre/second (m/s)

• Metre (m)

What is the time period of a wave?

• The height of a wave measured from rest to crest

• The number of complete waves that occur in one second

• How long it takes for one complete wave to pass a certain point

• How fast a wave travels in a given time

What is the unit of measurement for wave speed?

• Metre (m)

• Metre/second (m/s)

• Second (s)

• Hertz (Hz)

What is the definition of a wavefront?

• The vibrating part of a wave

• The number of complete waves that occur in one second

• The distance from one point on a wave to the same point on the next wave

• The time it takes for one complete wave to pass a certain point

How does a wave transfer energy?

• By changing its frequency

• By changing its wavelength

• By disturbing the medium through which it travels

• By moving matter from one place to another
