(a) Give one example of a transverse wave and one example of longitudinal wave.
(b) Fig 6 shows the displacement of a particle in a progressive wave incident on a boundary between deep and shallow regions.
(i) Complete the diagram to show what is observed after boundary (Assume no loss of energy)
(ii) Explain the observation in (i) above
(c) Water waves are observed as they pass a fixed point at a rate of
30 crests per minute. A particular wave crest takes 2s to travel between two fixed points 6m apart.
Determine for the wave:
(i) The frequency
(ii) The wavelength
