16.4 Exercise 17

Avg difficulty 2.5

The power versus time for a point on a string (μ=0.05kg/m)\left(\mu = 0.05 \text{kg}/\text{m}\right) in which a sinusoidal traveling wave is induced. The wave is modeled with the wave equation y(x,t)=Asin(20.93m−1x−ωt)y \left(x , t\right) = A \text{sin} \left(20.93 \text{m}^{−1} x - \omega t\right). What is the frequency and amplitude of the wave?
