Sample problem

A particular guitar string has a mass of 3.0 grams and a length of 0.75 m. A standing wave on the string has the shape shown in the simulation below - the wave has a frequency of 1200 Hz.

(a) What is the speed of the wave?

(b) What is the tension of the string?

(c) The wave on the string produces a sound wave. Does the sound wave have the same frequency, wavelength, or speed as the wave on the string?
