Answer:

The speed of sound for middle C is 345.01 m/s.

Explanation:

Given that,

The frequency of middle C is 261.63 Hz

The wavelength of middle C note used when playing or singing music, $\lambda=131.87\ cm=1.3187\ m$

We need to find the speed of sound for middle C. We know that the relation between speed, frequency and wavelength is given by the formula as follows :

$v=f\lambda\\\\v=261.63\ Hz\times 1.3187\ m\\\\v=345.01\ m/s$

So, the speed of sound for middle C is 345.01 m/s. Hence, this is the required solution.
