The equation of wave motion is Y = 6 (12 t - 0.02 x + 3 ) where x is in metre and time in second. The velocity of the wave is

Options

  1. A200 m/s
  2. B300 m/s
  3. C400 m/s
  4. D600 m/s

Correct answer

D. 600 m/s

Step-by-step solution

The standard equation of a travelling wave is Y = A ( t - kx + ) . Comparing the given equation Y = 6 (12 t - 0.02 x + 3 ) with the standard equation, we get: = 12 rad/s k = 0.02 rad/m The velocity of the wave is given by v = k . Substituting the values: v = 12 0.02 = 12 0.02 = 600 m/s. Answer: 600 m/s
