COMEDK · Physics · 16. Waves and Sound
In an experiment with sonometer a tuning fork of frequency \(256 \mathrm{~Hz}\) resonates with a length of \(25 \mathrm{~cm}\) and another tuning fork resonates with a length of \(16 \mathrm{~cm}\). Tension of the string remaining constant the frequency of the second tuning fork is
- A \(163.84 \mathrm{~Hz}\)
- B \(400 \mathrm{~Hz}\)
- C \(320 \mathrm{~Hz}\)
- D \(204.8 \mathrm{~Hz}\)
Answer & Solution
Correct Answer
(B) \(400 \mathrm{~Hz}\)
Step-by-step Solution
Detailed explanation
The wavelength of the sound is proportional to the length of wire. Also, the velocity of sound is same in both cases, so…
