The wave in a ripple tank is represented by the equation y = 0.60 sin (20t - 4x) where x and y are in cm and t in second. (a) Find the speed of the wave. (b) Deduce an equation to represent a wave on the ripple tank that has half the amplitude and twice the frequency but travels with the same speed in the opposite direction.
