Detailed Solution

The above statement is true.
The sound wave's wavelength is the distance between successive compression or rarefaction.
A wavelength is a distance between two adjacent compressions or rarefactions in sound waves.
In a transverse wave, one wavelength is defined as the distance between two adjacent crests or troughs.
The frequency of a sound wave is defined as the number of vibrations that occur or the number of compressions and rarefactions that occur in one second.
As a result, if the wavelength is λ and the frequency is f, the speed of the sound wave can be given as
v=λf
