A uniform tube of length 60.5 cm is hel vertically with its lower end dipped in water.A sound souece of frequency 500 Hz sends sound waves into the tube.When thr length of tube above water is 16 cm and again when it is 50 cm, the tube resonates with the source of sound.Two lowest frequencies(in Hz), to which tube will resonates when it is taken out of water, are (approximately).

Q3
A uniform tube of length 60 cm stands vertically with its lower end dipping into water. First two air column lengths above water are 15 cm and 45 cm, when the tube responds to a vibrating fork of frequency 500 Hz. Find the lowest frequency (in Hz) to which the tube will respond when it is open at both ends.

Q4
A long glass tube is held vertically, dipping into water, while a tuning fork of frequency 512 Hz is repeatedly struck and held over the open send. Strong resonance is obtained, when the length of the tube above the surface of water is 50 cm and again 84 cm, but not at any intermediate point. Find the speed of sound in air and next length of the air column for resonance.

Q5
A source of frequency 340 Hz is kept above a certical cylindrical tube closed at lower end. The length of the tube is 120 cm. Water is slowly poured in just enough to produce resonance. Then the minimum height (velocity of sound =340 m/s) of the water level in the tube for the resonance is
