A vibrating tuning fork is placed over the mouth of a burette filled with water. The tap of the burette is opened and the water level gradually starts falling. it is found that the sound from the tuning fork becomes very loud for a particular length of the water column.
Name the phenomenon taking place when this happens.

Q. A vibrating tuning fork, held over an air column of given length with its one end closed, produces a loud audible sound. Name the phenomenon responsible for it and explain the observation.

Q. A tuning fork whose natural frequency is 440 Hz is placed just above the open end of a tube that contains water. The water is slowly drained from the tube while the tuning fork remains in place and is kept vibrating. The sound is found to be enhanced when the air column is 60 cm long and when it is 100 cm long. Find the speed of sound in air in m/s.
