Fifty-one turning forks are arranged in order of increasing frequencies so that each fork gives 3 beats per second with the next. The last fork gives the fifth of the first. Calculate the frequency of the latter.

Fifty-six tuning forks are arranged in order of increasing frequencies so that each fork gives 4 beats per second with the next one. The last fork gives the octave of the first. Find the frequency of the first.

Sixty-four tuning forks are arranged in order of increasing frequency and any two successive forks give four beats per second when sounded together. If the last fork gives the occtave of the first, calculate the frequency of the latter [Hint: When two frequencies are such that one is double the other, the higher one is said to be an actave higher than the first and the lower one is to be an octave lower than the second.]

A set of 25 tuning forks is arranged in order of decreasing frequency. Each fork gives 3 beats with succeding one. The first fork is octave of the last. Calculate the frequency of the first and 16th fork.

A set of 22 tuning forks is arranged in a series of increasing frequencies. If each fork gives 5 beats per second with the preceding one and last one sounds with the octave of the first, then find the frequencies of the first and the last forks.

A set of 24 tuning fork is arranged in a series of increasing frequencies. If each fork gives 4 beats per second with the preceding one and the last sounds the ocatve of the first, find the frequencies of the first and the last forks.

56 tuning forks are so arranged in series that each fork gives 4 beats per second with the previous one.The frequency of the last fork is three times that of the first.The frequency of the fork is

A set of 31 tuning forks is arranged in series of decreasing frequency. Each fork gives 6 beats/sec. with the preceding one. The first fork is the octave of the last. The frequency of the last tuning fork is
