Water waves are transverse waves. Sound is a longitudinal wave. Describe the difference between transverse waves and longitudinal waves. In your account, draw a diagram of each type of wave. Sound contains regions of compression and regions of rarefaction. Describe what is meant by a compression and by a rarefaction. A ripple tank is used to demonstrate the reflection of water waves. Draw a labelled diagram of a ripple tank. Draw a diagram showing the reflection of waves from a plane barrier in a ripple tank. shows a water wave passing a floating log. The log is stationary. 6.0 m log water wave A The log is 6.0 m long and 5 complete waves take 10 seconds to pass point A. Determine the wavelength of the water waves, the frequency of the water waves, the speed of the water waves.

and Fig.4.2 are diagrams of a ripple tank being used to show two properties of waves. shows wavefronts approaching a barrier in the water. barrier wavefronts Complete to show the reflection of the wavefronts at the barrier. shows the wavefronts approaching shallow water above a piece of glass. wavefronts piece of glass beneath water Complete to show the wavefronts in the shallow water. As the wave passes into the shallow water, state what, if anything, happens to 1. the wave speed, 2. the frequency.

shows circular wavefronts produced at the centre of a circular ripple tank. 8.0 cm cork B cork A Two corks, A and B, float on the water in the ripple tank. They move up and down on the surface of the water as the wave passes. The wavelength of the wave is 8.0 cm. shows how the displacement of A varies with time. +2 0.25 0.50 0.75 1.00 1.25 time / s displacement / mm –2 State the amplitude of the vibrations of A as the wave passes. amplitude = The horizontal distance between A and B is half the wavelength of the wave. On , sketch a graph to show how the displacement of B varies with time. Use to determine the frequency of the wave. frequency = The distance between the centre of the ripple tank and its edge is 40 cm. Determine the time taken by a wavefront to travel from the centre of the tank to the edge. time =
