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 5 beats per second. The frequency of one of them is 250 Hz. When the other fork is slightly loaded, they produce 7 beats/s. Then the frequency of other tuning fork without loading is

16 tuning forks are arranged in increasing order of frequency. Any two consecutive tuning forks when sounded together produce 8 beats per second. If the frequency of last tuning fork is twice that of first, the frequency of first tuning fork 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 when sounded together produce 3 beats per second. On loading one of them with a little wax, 20 beats are heard in 4 seconds. Find its frequency if that of other is 386.

Two tuning forks when sounded together produce 5 beats per second. A sonometer wire of length 0.24 m is in unison with one of the forks. When the length of the wire is increased by 1 cm, it is unison with the other fork. Find the frequencies of the tuning forks.

Two tuning forks when sounded together produced 4beats//sec . The frequency of one fork is 256. The number of beats heard increases when the fork of frequency 256 is loaded with wax. The frequency of the other fork is

Two tuning forks when sounded together produced 4beats//sec . The frequency of one fork is 256. The number of beats heard increases when the fork of frequency 256 is loaded with wax. The frequency of the other fork is
