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 bought at the upper end of the tube and the velocity of sound is 330 m s –1 , then the total number of resonances obtained will be
Text Solution
Verified by ExpertsThe correct answer is:
B
Wavelength,
The resonance occurs at
i.e., at 
m 
m, 
m, 
As the length of the tube is only 
, hence 3 resonances will be observed.
