Question
A wire of length 40 cm which has a mass of 4gms oscillates in its second harmonic and sets the air column in the tube to vibrations in its fundamental mode as shown in figure. Assuming speed of sound in air as 340 m/s, find the tension in the wire.
- 11.56 N
- 12.54 N
- 13.46 N
- 11.36 N
The correct answer is: 11.56 N

A tuning fork of frequency 250 Hz produces 4 beats per second with a wire of length 25 cm vibrating in its fundamental mode. The beat frequency decreases when the length is slightly shortened. What could be the minimum length by which the wire be shortened so that it produces no beats with the tuning fork?
