Question

establish relationship between speed of sound its frequency and wavelength

Answer 1

We know that,
V=S/t ........(1)
Let ,
speed of sound=V
frequency =f
wavelength=w

V=S/t
V=w/t
V=w x 1/t
V=w x f ..........(f=1/t)

Answer 2

Speed =$\frac{ Distance }{Time}$
= $\frac{ lambda}{time}$


Frequency = $\frac{1}{Time. period(T)}$

Therefore speed(v) = lambda x $\frac{1}{Time. period(T)}$
= lambda( λ) x Frequency(f)


Therefore ,
v = λ x f
