Question

A note has a wavelength of 0.77955 m. If the speed of sound is 343.00 m/s, what pitch is this note?

Answer 1

The equation for wave speed is:


`v=\lambda * f`

where "v" is wave speed, "λ" is wavelength and "f" is frequency.

Given the wave speed is 343m/s and the wavelength is 0.77955m, we can rewrite the equation as:


`(v)/(\lambda) = f`

Substituting known values, we get:


`(343)/(0.77955) =f`


`f=439.9974344`

The pitch that's the closest to this value is Pitch A.
