Questions 6-8 refer to the same problem A sinusoidal wave with wavelength 2 m and amplitude 5 mm is traveling along the x axis. The wave is traveling in the -x direction at a speed of 2m/s At t = Os, the wave's phase at x = 3 m is op. Take p = 0 rad. Question 6 6 pts Write the displacement of the wave as a function D(x,t) = A sin(kx - wt+40). Give the values of A, k, w and po. Show your work. Draw a snapshot graph of the wave at t = 0 s from x = - 2m to x = +6m. Explain. Draw your graph on paper using a set of axes as given below, then upload your work.
