Question

A D note that is played by a piano has a frequency of 577 Hz. The speed of sound through the air is 343 m/s. What is the wavelength of the D note?

Answer 1

We have to use the wavelength is

$\lambda=\frac{v}{f}$

Where f = 577 Hz and v = 343 m/s.

$\lambda=\frac{343m/s}{577Hz}\approx0.60m$

Hence, the wavelength is 0.60 meters, approximately.
