Velocity of sound waves in air is ' V ' m / s . For a particular sound wave in air, path difference of ' x ' cm is equivalent to phase difference n . The frequency of this wave is

Options

  1. AVn x
  2. BV nx
  3. CVn 2 x
  4. D2 x V

Correct answer

C. Vn 2 x

Step-by-step solution

Phase difference, = 2 x Given = n ; = V f aligned & n = 2 xf V & f = nV 2 x aligned
