Coupled OscillatorsHardQuestion 31197

Question

In a Melde's experiment (string vibrations), resonance occurs when:
  1. A
    Frequency of vibration = any multiple of string's natural frequency
  2. B
    Frequency of vibration = natural frequency of string
    Correct
  3. C
    Only when string is vertical
  4. D
    Amplitude of vibrator equals string amplitude

Correct answer

Frequency of vibration = natural frequency of string

Explanation

Melde's experiment: frequency of the vibrating fork drives transverse waves in the string. Resonance (standing waves) occurs when the driving frequency matches one of the string's normal mode frequencies.
