In the experiment to determine the speed of sound using a resonance column:

Options

  1. AProngs of the tuning fork are kept in a vertical plane
  2. BProngs of the tuning fork are kept in a horizontal plane
  3. CIn one of the two resonances observed, the length of the resonating air column is close to the wavelength of s
  4. DIn one of the two resonances observed, the length of the resonating air column is close to half of the wavelen

Correct answer

A. Prongs of the tuning fork are kept in a vertical plane

Step-by-step solution

Length of air column in resonance is odd integer multiple of 4 . Correct option is (a).
