**1.**

For a fundamental vibration:

$\overline{){\mathbf{L}}{\mathbf{=}}\frac{\mathbf{\lambda}}{\mathbf{2}}}$

The basic equation connecting wave speed v, wavelength? and frequency f is

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 *f*_{1} and the string length L.
