Homework Statement
In a resonance tube experiment, a closed organ pipe of length 120 cm resonates ,when tuned with a tuning fork of length 120cm resonates,when tuned with a tuning fork of length 340 hz.If water is poured into the pipe ,then (speed of sound in air=340 ms^-1)
(A) minimum length of water coloumn to have resonance is 50cm
(B) the distance between two succesive nodes is 50 cm
(C)The maximum length of water coloumn to create resonance is 100cm
(D) None of the above
Homework Equations
The Attempt at a Solution
Before the water started filling
Wavelength=Velocity/frequency=1m
For a closed pipe,the resonance condition is
L=n λ/4
Substituting values
4 L/n =1
n=5
therefore - 2n+1=5
n=2
L=3λ/4
I am confused about the next part where there is water flowing into the coloumn.How will it affect the air column now[/B]
