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

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 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).

8 beats are produced per second, when two tuning forks (A and B) are vibrated togeter. The tuning fork A produces resonance in the air column of length 37 . 5 cm of and open pipe and the tuning fork B produces resonance in the air column of length 38 . 5 cm of same pipe. Determine the frequencies of the two tuning forks .

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 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 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.

The first resonating length of an air column , for a given tuning fork , is 16.5 cm and the second resonating length is 49.5 cm . If the velocity of sound in air is 300 m s^(-1) , find the frequency of tuning fork used .
