On sounding fork `A` with another tuning fork `B` of frequency `384 Hz , 6 beats` are produced per second .After loading the prongs of `A` with wax and then sounding it again with `B , 4 beats` are produced per second. What is the frequency of the tuning fork `A`.

When a tuning fork A of unknown frequency is sounded with another tuning fork B of frequency 256Hz, then 3 beats per second are observed. After that A is loaded with wax and sounded, the again 3 beats per second are observed. The frequency of the tuning fork A is

A tuning fork produces 4 beats per second with another 68. 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 ?

(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 tuning fork A of frequency 512 Hz sounded with another tuning fork B gives 5 beats/sec. On loading B with a piece of wax, and on sounding, again 5 beats/sec are produced. Calculate the frequency of fork B.

A tuning fork of frequency 100 when sounded together with another tuning fork of unknown frequency produces 2 beats per second. On loading the tuning fork whose frequency is not known and sounded together with a tuning fork of frequency 100 produces one beat, then the frequency of the other tuning fork is

Tuning fork A when sounded with a tuning for B of frequency 480 Hz gives 5 beats per second. When the prongs of A are loaded with wax, it gives 3 beats per second. The original frequency of A is

A tuning foork A of frequenct 260 c/s Hz produces 4 beats per second when sounded with a tuning fork B. the number of beats produced per second becomes 3. Then, what is the frequency of tuning fork B?

When a tuning fork of frequency 341 is sounded with another tuning fork, six beats per second are heard. When the second tuning fork is loaded with wax and sounded with the first fork, the number of beats is two per second. The natural frequency of the second tuning fork is
