The graph in Figure 1 shows the displacement versus position for the wave at t = 1:0 s. The graph in Figure 2 shows the displacement versus time for the wave at x = 1:0 m. Determine the displacement equation D(x,t) and the velocity of the wave. SHOW WORK
from the graphs we have
Amplitude A = 0.1m
wavelength =4m
time period T = 2s
speed V = wavelength / time period = 4/2 = 2m/s
we have
the equation of the wave is
D(x,t) = A sin (wt -kx)
D(x,t) = 0.1 sin(3.14t -1.57x)
