Two tunning forks `A and B` when sounded together produce ` 3 beats//s`. What are the possible frequencies of `B`, if the frequency of `A is 400` cycle//s ? How can you verify which of the possible values is correct ?

Two tuning forks when sounded together produce one beat per 0.4 s. Then the difference of their frequencies is

Two tuning forks when sounded together produce 4 beats per second. The first produces 8 beats per second. Calculate the frequency of the other.

Two tuning forks A and B produce 8 beat/s when sounded together. When B is slightly loaded with a wax the beats are reduced to 4 per sec. If the frequency of A is 512 Hz, the frequency of B is

When two tunning forks A and B are sounded together , 4 beats per second are heard . The frequency of the fork B is 384 Hz . When one of the prongs of the fork A is filled and sounded with B , the beat frequency increases , then the frequency of the fork A is

When two tuning forks A and B are sounded together, 4 beats per second are head. The frequency of the fork B is 348 Hz. When one of the prongs of the fork A is filled and sounded with B, the beat frequency increases, then the frequency of the fork A is

Two tuning fork when sounded together, produce 3 beats//s . One of the fork is in unison with 27 cm length of sonometer wire and other with 28 cm length of the same wire. The frequencies of the two tuning forks are

Two tuning forks A and B when sounded together produce 2 beats per second. A has a frequncy of 340 . It is now loaded and again sounded with B. It is found that the number of beats is 4 per second. Can you say decidedly what is the frequency of B from this observation?

Two tuning forks A and B give 4 beats/s when sounded together. If the fork B is loaded with wax 6 beats/s are heard. If the frequency of fork A is 320 Hz, then the natural frequency of the tuning fork B will be
