TS EAMCET · Physics · Waves and Sound
Two tuning forks of frequencies 320 Hz and 323 Hz are vibrated together. The time interval between a maximum sound and its adjacent minimum sound heard by an observer is
- A \(\frac{1}{6} \mathrm{~s}\)
- B \(\frac{1}{3} \mathrm{~s}\)
- C \(\frac{1}{12} \mathrm{~s}\)
- D \(\frac{1}{9} \mathrm{~s}\)
Answer & Solution
Correct Answer
(A) \(\frac{1}{6} \mathrm{~s}\)
Step-by-step Solution
Detailed explanation
\(f_b = |320 - 323| = 3 \mathrm{~Hz}\) \(t = \frac{1}{2f_b} = \frac{1}{2 \times 3} = \frac{1}{6} \mathrm{~s}\)
