A transverse wave propagating along x -axis is represented by y(x, t)=8.0 (0.5 x-4 t- / 4) where x is in metres and t is in seconds. The speed of the wave is:

Options

  1. A8 ~m / s
  2. B4 m / s
  3. C0.5 m / s
  4. D1 2 ~m / s

Correct answer

A. 8 ~m / s

Step-by-step solution

It is given that: y (x₁ t )=8.0 (0.5 x-4 t- 9 ) Compare this equation with standard equation y=a ( 2 x - 2 t ~T + ) we have aligned 2 & =0.5 & = 2 0.5 =4 ~m 2 T & =4 T & = 1 2 U= 1 T & = 1 y₂ =2 H ₂ . aligned
