1 (a) A student reading his physics book on a lake dock notices that the distance between two incoming wave crests is 0.75 m, and he then measures the time of arrival between the crests to be 1.6 s. Determine the (i) frequency (ii) speed of the waves. [4 marks) (b) ( 16 cm m 4 cm FIGURE 1 FIGURE 1 shows a progressive wave travelling at a speed of 24 ms to the right and the frequency of the wave is 600 Hz. (1) Determine the wave number. (ii) Calculate the angular frequency (iii) Write the wave equation. [6 marks] A progressive wave is described by y = 5 sin 27(10t -) where x, y are in cm and in s. Calculate the (1) speed of the wave. (ii) vibrational velocity at 1 = 0 s, for the particle is at x = 5.0 cm. 17 marks) (c) I
