The wave speed in a stretched string depends on the string's tension T and mass per unit length? (also called the "linear mass density") with the equation

1. If the string's length is L, what is the fundamental wavelength ?1?

(I already got this answer, it is 2L)

2. Derive a formula for the speed of the wave in terms of the fundamental frequency f1 and the string length L.

v=
