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

Text Solution

Verified by Experts

The correct Answer is:
144 Hz and 99 Hz
Given that `n_(1) = 2n_(25)`
`n_(1) - n_(25) = 24 xx 3`
`n_(25) = 72 Hz`
`n_(1) = 2 xx 72 = 144 Hz`
`n_(16) = n_(1) - 3 xx 15 = 99 Hz`
