(a(i))[1]
From Fig. 6.1, determine the amplitude of the wave.
(a(ii))[1]
From Fig. 6.1, determine the wavelength of the wave.
(b)[2]
Calculate the frequency of the wave.
(c)[6]
(i) On Fig. 6.2, sketch the pattern of three crests after the wave has passed through the opening in the barrier. (ii) Water is added to the tank, and the speed of a wave in the deeper water is greater than that in the shallower water. The frequency of the wave stays constant but its wavelength is different. 1. State and explain how the wavelength in the deeper water has changed. 2. Apart from the wavelength change, describe one further difference in the crest pattern after the wave passes through the opening.
