4 Generating a Travelling Wave µ A very long string with μ = 2.0 g/m is stretched along the x-axis with a tension of 5.0 N. At x = 0 it is tied to a 100 Hz simple harmonic oscillator that vibrates perpendicular to the string with an amplitude of 2.0 mm. The oscillator is at its maximum positive displacement at t=0 seconds. Problem 4.1. What is the wave speed of the oscillation travelling through the string? Problem 4.2. The general equation for the displacement is: s(x,t) = Smsin(kxwt + 0) Write the displacement equation for the travelling wave on the string described in the ques- tion. You will need the amplitude ym, the phase constant o, the angular frequency omega and the wavenumber k. Problem 4.3. At t = 5.0 ms, what is the string's displacement at a point 2.7 meters from the oscillator? (make sure your calculator is set to radians)
