This content was COPIED from BrainMass.com - View the original, and get the already-completed solution here!

A vibrating stretched string has length 38 cm, mass 25 grams and is under a tension of 30 newtons. What is the frequency to the nearest Hz of its 3rd harmonic?

If the source of the wave was an open organ pipe of the same length as the wire, what would be the frequency of the 2th harmonic?
