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.

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 waves of wavelengths 52.5 cm and 52 cm produces 5 beats per second.their frequencies are

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

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 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 .

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

Two sound wave of wavelength 0.80 m and 0.81 m produce 8 beats per second in air. The frequency of the two waves are respectively:

A closed organ pipe and an open organ pipe of same length produce 2 beats/second while vibrating in their fundamental modes. The length of open organ pipe is halved and that of closed pipe is doubled. Then, the number of beats produced per second while vibrating in the fundamental mode is
