i. Name the type of wave generated on the water surface.
ii. The cork is observed to stay put despite passing water waves. Explain this observation.
iii. It was estimated that successive waves pass the cork every 0.25 seconds. If the speed of the waves is 0.28m/s, determine
the frequency and wave length of the waves at that point.
iv. Sketch the wavelength as viewed from a point above the ripple tank.
