Question

how are wavelength and frequency of sound related to its speed?...

Answer 1

velocity=frequency*wave length

Answer 2

That number, also known as the frequency, will be larger for a short-wavelength wave than for a long-wavelength wave. The equation that relates wavelength and frequency for electromagnetic waves is: λν=c where λ is the wavelength, ν is the frequency and c is the speed of light.this is their relationship.
