By wiggling one end, a sinusoidal wave is made to travel along a stretched string that has a mass per unit length of 22.0 g/m. The wave may be described by the wave function y 0.20 sin (0.90x-42) where x and y are in meters and t s in seconds. 1. (a) Determine the speed of the wave. Is the wave moving in the +x direction or the -x direction? b) What is the tension in the stretched string? (c)...

A wave is traveling down the length of a string at some speed, v. If we wanted to double the speed of the wave, which of the following would be a possible way to do so? (Select all that apply.) Increase the mass of the string by two times. Reduce the mass of the string by half. Double the tension in the string. Reduce the mass of the string by one-fourth. Reduce the linear density of the string by one-fourth.
