Melde's ExperimentMediumQuestion 31345

Question

In Melde's longitudinal mode, string vibrates at half the frequency of vibrator. String is in resonance when vibrator gives n vibrations per second and string gives:
  1. A
    n vibrations per second
  2. B
    2n vibrations per second
  3. C
    n/2 vibrations per second
    Correct
  4. D
    n² vibrations per second

Correct answer

n/2 vibrations per second

Explanation

In longitudinal mode, string frequency = half of vibrator frequency. One vibrator oscillation creates one complete loop.
