Velocity of sound waves in air is 330 ~m / s . For a particular sound wave in air, path difference of 40 cm is equivalent to phase difference of (1.6) . The frequency of this wave is

Options

  1. A165 Hz
  2. B150 Hz
  3. C660 Hz
  4. D330 Hz

Correct answer

C. 660 Hz

Step-by-step solution

Given: =1.6 and = V f We know, Phase difference = 2 x aligned & 1.6 = 2 x f 330 f= 1.6 330 2 40 0.01 & f=660 ~Hz aligned
