Progressive Wave Equation

A traveling wave is described by the equation y(x,t)=[0.05sin⁡(8x−4t)]y(x, t) = [0.05\sin(8x - 4t)] m

The velocity of the wave is [All the quantities are in SI unit]

Show answer and solution

Answer: (c)

  1. k=8 m−1k = 8\text{ m}^{-1}, ω=4 rad/s\omega = 4\text{ rad/s}
  2. v=ωk=48=0.5 m/sv = \dfrac{\omega}{k} = \dfrac{4}{8} = 0.5\text{ m/s}
  3. So the answer is (c) 0.5 m s−10.5\text{ m s}^{-1}.
