Question

establish a relation between speed wavelength & frequency
of wave​

Answer 1

speed of sound = V

wavelength = λ

frequency = v

the time period of a wave is represented by = T = 1/v

In time T, a distance of wave length v is covered  

so the speed of sound = V = λ/T

or V = λv

Answer 2

velocity= wavelength× frequency.
