Question

A wave passes your house which has originated at a distance of x = 15m away from your house at the time t = 0s. It is traveling at a speed of 50 m/s. The displacement of the wave as it passes your house is 4m. It has a frequency of 2Hz. You also notice that the maximum displacement of the wave is 5m.

(a) Write the equation for the displacement of this wave as a function of position and time.

(b) Draw a history graph (at x = 0m) and a snapshot graph (at t = 0s).
