Prong of a vibrating tuning fork is in contact with water surface. It produces concentric circular waves on the surface of water. The distance between five consecutive crests is 0.8 m and the velocity of wave on the water surface is 56 ~m / s . The frequency of tuning fork is

Options

  1. A256 Hz
  2. B280 Hz
  3. C341 Hz
  4. D512 Hz

Correct answer

B. 280 Hz

Step-by-step solution

aligned & = Distance between crests No.of crest -1 = 0.8 4 =0.2 ~m & v = n n = v & n = 56 0.2 =280 ~Hz aligned
