A transverse wave is represented by the equation y=2 (30 t-40 x) and the measurements of distances are in meters, then the velocity of propagation is

Options

  1. A15 ms -1
  2. B0.75 ms -1
  3. C3.75 ms -1
  4. D300 ms -1

Correct answer

B. 0.75 ms -1

Step-by-step solution

We have y=2 (30 t-40 x) The standard transverse wave is y=A ( t-k x) So, =30 and k=40 On comparing, we get v= k = 30 40 =0.75 ~m / s
