Question

If the distance between successive compressions and rarefactions is 1m and velocity of sound is 360m/s, then the frequency is

Answer 1

Given,

Distance between successive compressions and rarefactions = Wavelength = 1m
Velocity of sound = 360m/s
According to the formula,
Velocity = frequency *Wavelength
360=f*1
f=360Hz !!!ANSWER!!!

The question is easy but the catch is that:
Distance between successive compressions and rarefactions is also known as Wavelength.

Answer 2

Distance between successive compressions and rarefactions is 1m.
So wavelength is 1m.
We know that velocity= frequency × wavelength
Or frequency=Velocity / Wavelength= 360/1=360 hertz
