COMEDK · Physics · 16. Waves and Sound
In Melde's experiment in the transverse mode, the frequency of the tuning fork and the frequency of the waves in the string are in the ratio
- A \(2: 1\)
- B \(4: 1\)
- C \(1: 1\)
- D \(1: 2\)
Answer & Solution
Correct Answer
(C) \(1: 1\)
Step-by-step Solution
Detailed explanation
In Melde's experiment, the change in frequency is produced when the tension in the string is increased. So, a resonance is required between tuning fork and the frequency of waves produced. For this, the frequencies of both should be same or their ratio be \(1: 1\).
