  1. If the tension in a 2 m string was provided by a 150g mass, and the µ for the sting was 1.0 g/m, what is the speed of a wave traveling along the string, and what is the fundamental frequency for a standing wave on this string?
  2. If you doubled the mass density of the string and tripled the hanging mass, what would happen to the fundamental frequency of the standing wave?
