Wave

What does a wave transfer?

• molecules

• energy

• matter

• force

As a transverse wave passes, the particles of the medium oscillate ___________.

• parallel to the direction of wave travel

• in phase with one another

• perpendicular to the direction of wave travel

• with different frequencies

Which of the following is an example of longitudinal waves?

• Waves in a ripple tank

• Light waves in air

• A vibrating guitar string

• Sound waves produced by a vibrating guitar string

The figure below shows the displacement-time graph of a particle in a transverse wave. If its speed is 2 cm/s, which of the following pairs of amplitude and wavelength is correct?

• Amplitude = 0.02 cm

  Wavelength = 0.006 cm

• Amplitude = 0.003 cm

  Wavelength = 0.02 cm

• Amplitude = 0.003 cm

  Wavelength = 0.04 cm

• Amplitude = 0.006 cm

  Wavelength = 0.04 cm

A vibrating dipper of frequency 3 Hz produces water waves in a ripple tank. Which of the following is a possible wavelength and speed of the waves?

• Wavelength = 3 cm

  Speed = 1 cm/s

• Wavelength = 15 cm

  Speed = 5 cm/s

• Wavelength = 3 cm

  Speed = 6 cm/s

• Wavelength = 4 cm

  Speed = 12 cm/s

The diagram shows a ball floating in a tank of water.

Which diagram shows the movement of the ball as the wave passes?

• 
• 
• 
• 

The diagram shows the pattern of waves in a ripple tank.

What does the pattern show?

• waves being reflected

• waves being refracted

• waves changing frequency

• waves changing speed

In an experiment using a ripple tank, plane wavefronts arrive at a plane surface.

 

Which row correctly describes the waves after they are reflected from the surface?

• Larger speed

  &

  Shorter wavelength

• Smaller speed

  &

  Shorter wavelength

• Same speed

  &

  Longer wavelength

• Same speed

  &

  Same wavelength

Water waves refract at a boundary between deep water and shallow water.

 

What is the effect on the frequency, wavelength and speed of the waves at the boundary? 

• Frequency = changes

  Wavelength = changes

  Speed = same

• Frequency = changes

  Wavelength = same

  Speed = same

• Frequency = same

  Wavelength = changes

  Speed = changes

• Frequency = same

  Wavelength = same

  Speed = changes
