When a vibrating tuning fork is placed on a sound box of a sonometer, 8 beats per second are heard when the length of the sonometer wire is kept at 101cm or 100cm. Then the frequency of the tuning frok is (consider that the tension in the wire is kept constant)

A

1616 Hz

B

1608 Hz

C

1632 Hz

D

1600 Hz

Text Solution

Verified by Experts

The correct Answer is:
B
`n_1l_1=n_2l_2`
`(n+8)100=(n-8)101`
`100n+800=101n-808`
`n=1608`

A string 25 cm long and having a mass of 2.5g is under tension. A pipe closed at one end is 40 cm long. When the string is set vibrating in its firsy overtone and the air in the pipe in its fundamental frequency, 8 beats per sec are heard. It is observed that decreasing the tension in the string decreases the beat frequency. If the speed of sound in air is 320 m/s, find the tension in the string.
