Tunnig Fork

(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?

25 tunning forks are arranged in series in the order of decreasing frequency. Any two successive forks produce 3 beats/sec. If the frequency of the first turning fork is the octave of the last fork, then the frequency of the 21st fork is

A tuning fork of frequency of 512Hz when sounded with unknown tunning fork produces 5 beats/sec. If arms of the unknown fork are filed then it produces only 3 beats/sec. Find the frequency of unknown tunning fork.

50 tunning forks are arranged in increasing order of their frequencies such that each gives 4 beats/sec with its previous tuning fork. If the frequency of the last fork is octave of the first, then the frequency of the first tuning fork is

Tuning fork A of frequency 205 Hz produces 5 beats/sec with another fork B. After filing the tuning fork B, it produces 3 beats/sec with A. What was the frequency of the fork B before filling?

A tunning fork produces 6 beast/s when sounded with a tuning fork of frequnecy 256 Hz. The same tunning fork when sounded with another tunning fork of frequency 252 Hz produces 2 beat/s. Find the frequency of the tunning fork.

When a tuning fork vibrates, the waves produced in the fork are

Two tuning forks having frequency 256 Hz (A) and 262 Hz (B) tuning fork. A produces some beats per second with unknown tuning fork, same unknown tuning fork produce double beats per second from B tuning fork then the frequency of unknown tuning fork is :-

The prongs of the tuning fork are filled a little, the frequency of the tuning fork after filled
