Question

Middle C, also known as do on the fixed do-solfge scale, is a note used when playing or singing music. The frequency of middle C is 261.63 Hz, and the wavelength is 131.87 cm. What is the speed of sound for middle C?

Answer 1

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

Step-by-step 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* 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.
