7. As well, the speed of the wave traveling on the guitar string depends on the tension of the string ( T ) and the linear mass density of the string ( ?), in fact,  the root frequency for a string is proportional to the square root of the tension, inversely proportional to its length, and inversely proportional to the square root of its linear mass density.
