A sound wave is travelling with a frequency of 50 ~Hz . The phase difference between the two points in the path of a wave is 3 . The distance between those two points is (Velocity of sound in air =330 ~m / s )

Options

  1. A1.1 m
  2. B0.6 m
  3. C2.2 m
  4. D1.7 m

Correct answer

A. 1.1 m

Step-by-step solution

Phase difference = 2 x aligned & = v f = 330 50 =6.6 ~m & x = 2 = 6.6 2 3 = 6.6 6 =1.1 ~m aligned
