# If a violin and a flute each play 256 Hz tones. Which wave has the longer wavelength?

The relationship between these is $v = f \lambda$.
where $v$ is the speed of sound, $f$ is the frequency (in Hz), and $\setminus \lambda$ is the wavelength.
Since the speed of sound will not change with the instrument being played (it only changes depending on the medium through which it travels), and the frequency is also the same, the wavelength ($\lambda$) should also be the same.
