A transverse wave travels 9.75 m to the right in 9.20 s. As it passes an element of the medium, the change in height of the medium is 35.6 cm. The medium takes 4.50 s to return to the maximum height as the wave passes it. Part 1) What is the speed of the wave? m/s Part 2) Write down an equation to describe the wave if at t = 4.65 s the element of the string at x = 7.35 m is 5.53 cm below its equilibrium position. Evaluate the expression as much as possible (ie. do not leave in terms of T). y(x, t) = sin( m Part 3) What is the speed of the element of string in Part 2? m/s
