m The wave shown in the figure is travelling in the positive x - direction with a wave speed of 300- a) Given that the figure represents the wave at time t = 0.0 s, write down an equation describing the wave. b) What would change (if anything) in the figure and in your equation if the wave were traveling in the negative x - direction instead? The wave shown in the figure is travelling in the positive x-direction with a wave speed of 300 m/s. y (m) 0.06 0.04 0.02 O -0.02 -0.04 -0.06 O 0.1 02 x (m) 0.3 0.4 0.5
