A sound wave is described byD(y,t) = (0.0200 mm) X sin [(8.96 rad/m) y + (3140 rad/s) t + pi/4rad] where y is in m and t is in s.
*The wave is traveling in the negative y direction, the axis isoscillating on the y-axis, the wavelength = .701. The wave speed; v = 350 m/s, The period of oscillation: T = 2.00 ms
The instructions ask that I draw a displacement vs time graph D(y=1.00 m, t) at y = 1.00 m from t = 0s and to t = 4.00 ms
I have these coordinates thus far:
0,-0.006
0.1,-0.012
0.2,-0.016
0.3,-0.019
0.4,-0.02
0.5,-0.019
0.6,-0.016
0.7,-0.012
0.8,0.006
0.9,0
1.0,006
However this only accounts for 1/2 the period I think. I need 2full periods.What are the rest of the coordinates?
