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 the velocity of sound is `340 m//s`, 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 , 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 tuning fork is held over a water column with one end closed and the other open. As the water level is allowed to fall, a loud sound is heard for water levels separated by 17 cm. If the speed of sound in air is 340 m/s, the frequency of the tuning fork is:
