Two tubes of length 50 cm and 51 cm, closed at one end, produce 35 beats in 10 second, when sounded with their fundamental notes . Neglecting end correction , find the velocity of sound in air.

Two open pipes of lengths 50 cm and 51 cm produce 6 beats per second when emitting their fundamental frequencies. Neglect end-corrections and calculate the velocity of sound.

If two open organ pipes of length 50 cm and 51 cm sounded together produce 7 beats per second , the speed of sound is

Two waves of wavelength 50 cm and 51 cm produce 12 beat/s . The speed of sound is

Two similar open organ pipes of length 50 cm and 50.5 cm produce 3 beats per second when sounded together. The velocity of sound in air is

Two closed organ pipes of length 100 cm and 101 cm product 16 beats is 20 sec, When each pipe is sounded in its fundamental mode calculate the velocity of sound .

The shortest length of resonating air column closed at one end is 7 cm when a tuning fork of frequency 480Hz is used.If inner diameter of the tube is 3 cm, find velocity of sound in air.

Two sound waves having wavelengths 81 cm and 82.5 cm produce 8 beats per second. Calculate the speed of sound in air.

Wave length of two notes in the air are [ 70/ 153] m and [70 / 157] m . Each of these notes produces 8 beats per second with a tuning fork of fixed frequency . Find the velocity of sound in the air and frequency of the tuning fork.

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
