Question

The frequency of the middle F note on a piano is `349.23` `Hz`. What is the wavelength of this note in centimeters?

The speed of sound in air is `343.06` `ms^-1`.

Answer 1

We use the wave equation `v=f\lambda`, and rearrange to make `\lambda` the subject: `\lambda=v/f=343.06/349.23=0.982` `m=98.2` `cm`
