A vibrating string produces 2 beats per secod when sounded with a turning fork of frequency `256Hz`. Slightly increasing the tension in the string produces 3 beats per second. The initial frequency of the string may have been

A tuning fork of frequency 280 Hz produces 10 beats per see when sounded with a vibrating sonometer string. When the tension in the string increases slightly, it produces 11 beats per see. The original frequency of the vibrating sonometer string is :

A tuning fork of frequency 512 Hz produces 6 beats per sec. with vibrating string of an instrument. On increasing the tension in the string, the beat frequency reduces to 3 beats/sec. Find the original frequency of the instrument.

A tuning fork of frequency 256 Hz is producing 5 beats/sec with the vibrating string of a sitar. On increasing the tension in the string, the beat frequency becomes 3 beats/sec. The initial frequency of sitar before increasing the tension is

(a) A tuning fork produces 4 beats per second with another tuning fork of frequency 256 Hz . The first one is now loaded with a little wax and the beat frequency is found to increase to 6 per second. What was the original frequency of the tuning fork ? (b) A plano wire A vibrates at a fundamental frequncy of 600 Hz . A second identical wire B produces 6 betas per second with it, when of the tension in A is slightly increased. Find the ratio of the tension in A to the tension to B . ( c) A tunnig fork if frequency 256 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 whech the wire be shortened so that it produces no beats with the tuning fork?

A vibrating string of certain length l under a tension T resonates with a mode corresponding to the first overtone (third harmonic) of an air column of length 75cm inside a tube closed at one end. The string also generates 4 beats per second when excited along with a tuning fork of frequency n . Now when the tension of the string is slightly increased the number of beats reduces 2 per second. Assuming the velocity of sound in air to be 340 m//s , the frequency n of the tuning fork in Hz is
