A wave is represented by the equation y=0.5 (10 t-x) metre It is a travelling wave propagating along +x direction with velocity

Options

  1. A10 ~m ~s ⁻¹
  2. B20 ~m ~s ⁻¹
  3. C5 ~m ~s ⁻¹
  4. DNone of these

Correct answer

A. 10 ~m ~s ⁻¹

Step-by-step solution

Compare the given eqn y=0.5 (10 t-x) with the standard form aligned & y=r [ 2 t T + 2 x ] & 2 T =10, 2 =1 & v= T = 10 1 =10 ~m / s aligned
