There are 26 tuning forks arranged in the decreasing order of their frequencies. Each tuning fork gives 3 beats with the next. The first one is octave of the last. What is the frequency of 18 th tuning fork?

Options

  1. A100 Hz
  2. B99 Hz
  3. C96 Hz
  4. D103 Hz

Correct answer

B. 99 Hz

Step-by-step solution

Each tuning forck gives 3 beats with the next, so the difference in the frequencies of two consecutive forks is 3 . ∴f26=f1+(n−1)×−3f=2f+(26−1)×−3f=75 Hz.\begin{aligned} \therefore \quad f_{26} & =f_1+(n-1) \times-3 \\ f & =2 f+(26-1) \times-3 \\ f & =75 \mathrm{~Hz} .\end{aligned}\thereforeFrequencyof18thtuningforkFrequency of 18 th tuning forkf18=f1+(18−1)×−3=2×75+17×−3=150−51=99 Hz\begin{aligned} f_{18} & =f_1+(18-1) \times-3 \\ & =2 \times 75+17 \times-3 \\ & =150-51=99 \mathrm{~Hz}\end{aligned}$
