The equation of a simple harmonic progressive wave is given by y=A (100 t-3 x) . Find the distance between 2 particles having a phase difference of 3 .

Options

  1. A9 ~m
  2. B18 ~m
  3. C6 ~m
  4. D3 ~m

Correct answer

A. 9 ~m

Step-by-step solution

Given, y=A (100 t-3 x) The general equation, aligned & & y &=A ( t-k x) & & k &=3 aligned and k= 2 or array l = 2 k = 2 3 array Phase difference, = 3 2 x= 3 or array l x- 3 2 x= 3 2 3 2 array Distance, x= 9 ~m
