Progressive Wave Equation

A wave travelling in positive X-direction with a == 0.2 m, velocity = 360 ms−1{}^{-1} and λ=\lambda = 60 m, then correct expression for the wave is

Show answer and solution

Answer: (c)

  1. f=vλ=36060=6 Hzf = \dfrac{v}{\lambda} = \dfrac{360}{60} = 6\text{ Hz}
  2. Wave along +x+x: y=asin⁡2π(ft−xλ)y = a\sin 2\pi\left(ft - \dfrac{x}{\lambda}\right)
  3. y=0.2sin⁡[2π(6t−x60)]y = 0.2\sin\left[2\pi\left(6t - \dfrac{x}{60}\right)\right]
  4. So the answer is (c).
