Question

A musical note has a frequency of 512 Hz. If the wavelength of the note is .685 m, what is the speed of the sound of that note?

Answer 1

I got `351m/s`

Explanation:

You can use the relationship where the speed `v` is related to wavelength, `lambda`, and frequency, `f`, as:

`v=lambda*f`

Or:
`v=0.685*512=350.72~~351m/s`
