A glass tube of 1.0 m length is filled with water, the water can be drained out slowly at the bottom of the tube. If a vibrating tuning fork of frequency 500 Hz is brought at the upper and of the tube and the velocity of sound is 330 m/s then the total no. of resonances obtained will be –
Text Solution
Verified by ExpertsThe correct answer is:
B
The resonance lengths are:
and 
As 
is greater than 
, so allowed resonances are only three
