Two tuning forks A and B give 9beats in 3 seconds. A resounds with a closed column of air 15cm long and B with an open column 30.5 cm long. Calculate their frequencies (neglect end correction).

Two tuning fork A and B give 5 beats // sec. A resounds with a closed column of air 15 cm long and B with an open column of air 30.5 cm long. Calculate their frequecies. Neglect end correction.

Two tuning forks A and B give 18 beats "in" 2 s . A resonates with one end closed air column of 15 cm long and B with both ends open column of 30.5 long. Calculate their frequencies.

Two tuning forks A and B give 18 beats "in" 2 s . A resonates with one end closed air column of 15 cm long and B with both ends open column of 30.5 long. Calculate their frequencies.

Two tuning forks A and B give 5 beats/s. A resonates with a column of air 15 cm long, closed at one end, and B with a column 30.5 long, open at both ends. Neglecting end correction, the frequencies of A and B are respectively

Two tuning forks A and B gives 6 beat/s. The fork A resonates with a closed end air column of length 15cm and the fork B with an open air column of length 30.5cm . If the air in both the cases vibrates in the air fundamental modes, then the frequencies of fork A and B will be

6 beats are produced in 3 seconds by two tuning forks T and T'. T resounds with a closed air column 20 cm long and T' is resounding with an open column 42 cm long. Neglecting end correction, find the frequencies of two forks.

Two tuning forks give 4 beats/s when sounded together. First tuning fork resounds with a closed air column 20 cm long and second tuning fork resounds with an open air column 40.5 cm long. Determine the individual frequencies of the two tuning forks neglecting end correction.

A tuning fork gives 15 beats per second when sounded with a sonometer wire of length 200 cm and 20 beats per second with that of length of 250 cm. calculate the frequency of the fork.

In a resonance tube experiment , a tuning fork resonates with an air column 10 cm long and again resonates when it is 32.2 cm long. Calculate the wavelength of wave and the end correction .

Two tuning forks A and B are sounded together and 8 beats//s are heard . A is in resonance with a column of air 32 cm long in a pipe closed at one end and B is increased by one cm . Calculate the frequency of fork .
