Frequency of a standing wave:

$\overline{){\mathbf{f}}{\mathbf{=}}\frac{\mathbf{n}\mathbf{v}}{\mathbf{2}\mathbf{L}}}$, where n is the number of waves, v is the wave speed, and L is the length of the string.

A 2.5 m long string is fixe at both ends and tightened until the wave speed is 40 m/s.

What is the frequency of the standing wave shown in the figure?
