Progressive Wave Equation

The equation of a sound wave is y=0.0015sin⁡(62.4x+316t)y = 0.0015\sin(62.4x + 316t). The wavelength of this wave is

Show answer and solution

Answer: (c)

  1. k=62.4k = 62.4
  2. λ=2πk=6.2862.4≈0.1\lambda = \dfrac{2\pi}{k} = \dfrac{6.28}{62.4} \approx 0.1 unit
  3. So the answer is (c) 0.10.1 unit.
