The concept required to solve this problem is related to the wavelength.
The wavelength can be defined as the distance between two positive crests of a wave.
The waves are in phase, then the first distance is
And out of the phase when
Thus the wavelength is
Here,
Wavelength
If we rearrange the equation to find it, we will have
Therefore the wavelength of the sound is 20cm.
