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 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 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 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.

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 .

Two tuning forks when sounded together give 8 beats per second. When tuning fork A is sounded with air column of length 37.5 cm closed at one end, resonance occurs in its fundamental mode. Tuning fork B gives resonance with air column of length 38.5 cm and is closed at one end in its fundamental mode. Find the frequencies of tuning forks.

Two tuning forks A and B sounded together give 8 beats per second. With an air resonance tube closed at one end, the two forks give resonances when the two air columns are 32 cm and 33 cm respectively. Calculate the frequenciec of forks.

A tuning fork A of frequency 512 Hz sounded with another tuning fork B gives 5 beats/sec. On loading B with a piece of wax, and on sounding, again 5 beats/sec are produced. Calculate the frequency of fork B.

A tuning fork of frequency 480 Hz resonates with a tube closed at one end of length 16 cm and diameter 5cm in fundamental mode. Calculate velocity of sound in air.
