A progressive wave of frequency 400 Hz is travelling with a velocity 336 ~m / s . How far apart are the two points which are 60^ out of phase?

Options

  1. A0.14 m
  2. B0.21 m
  3. C0.24 m
  4. D0.28 m

Correct answer

A. 0.14 m

Step-by-step solution

Phase difference ( )=60^ or 3 rad Path difference = 2 = 2 3 = 6 Path difference = 6 = v n 1 6 ( v= n ) Substituting given values, Path difference = 336 400 1 6 =0.14 ~m
