A long glass tube is held vertically in ...

A long glass tube is held vertically in water. A tuning fork is struck and held over the tube. Strong resonances are observed at two successive lengths 0.50 m and 0.84 m above the surface of water. If velocity of sound is `340 m s^(-1)`, then the frequency of the tuning fork is

A

`128 Hz`

B

`256 Hz`

C

`384 Hz`

D

`500 Hz`

Text Solution

Verified by Experts

The correct Answer is:
D
` lambda = 2( x_(2) - x_(1)) = 2 (0.84 - 0.50) = 0.68`
` n = (v)/(lambda) = ( 340)/( 0.68) = 500 Hz`

A long glass tube is held vertically in water . A tuning fork is struck and held over the tube . Strong resonances are observed at two successive lengths 0.50 m and 0.84 m above the surface of water . If the velocity of sound is 340 m//s , then the frequency of the tuning fork is

A long glass tube is held vertically , dipping into water, while a tuning fork of frequency 512 H_(Z) is respeatedly struck and held over the open end. 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 of sound in air and next length of the air column for resonance.

In a resonance tube the first resonance with a tuning fork occurs at 16 cm and second at 49 cm . If the velocity of sound is 330 m/s , the frequency of tuning fork is

A vibrating string of certain length l under a tension T resonates with a mode corresponding to the first overtone (third harmonic) of an air column of length 75cm inside a tube closed at one end. The string also generates 4 beats per second when excited along with a tuning fork of frequency n . Now when the tension of the string is slightly increased the number of beats reduces 2 per second. Assuming the velocity of sound in air to be 340 m//s , the frequency n of the tuning fork in Hz is

In a resonance tube, using a tuning fork of frequency 325 Hz, two successive resonance lengths are observed at 25.4 m and 77.4 cm respectively. The velocity of sound is air is

A fork of frequency 250 Hz is held over a tube and maximum resonance is obtained when the column of air is 0.31 m or 0.97 m. Determine (i) the velocity of sound (ii) the end correction and (iii) the radius of the tube.

A standing tuning fork of frequency f is used to find the velocity of sound in air by resonance column appartus. The difference two resonating lengths is 1.0 m . Then the velocity of sound in air is

A tuning fork of frequency 440 Hz resonates with a tube closed at one end of length 18 cm and diameter 5 cm in fundamental mode. The velocity of sound in air is

In determination of velocity of sound in air using resonance column tube, radius of cylindrical tube is 1 cm and frequency of tuning fork is 256 Hz. If velocity of sound is 340 m/s then length of air column in the tube when first resonance occurs, is

A hollow metallic tube of length L and closed at one end produce resonance with a tuning fork of frequency n. The entire tube is then heated carefully so that at equilibrium temperature its length changes by l . If the change in velocity V of sound is v, the resonance will now produced by tuning fork of frequency :-
