Question

Give the relation among speed of sound, wavelength and frequency .

Answer 1

speed of sound = freuency x wavelength

Answer 2

Wavelength=Distance travelled by the wave in one time period i.e. in T second.
= wave velocity*Time period
=V*T
wavelength=V*T
but T=1/frequency
wavelength=V*1/frequency
therefore
V=frequency*wavelength

hope it helped u
