Progressive Wave Equation

A progressive wave of frequency 50 Hz is travelling with velocity 350 m/s through a medium. The change in phase at given time interval of 0.01s is

Show answer and solution

Answer: (c)

  1. At a fixed point, phase changes with time as Δϕ=ω Δt=2πf Δt\Delta\phi = \omega\,\Delta t = 2\pi f\,\Delta t.
  2. Δϕ=2π×50×0.01=π\Delta\phi = 2\pi \times 50 \times 0.01 = \pi rad
  3. So the answer is (c) π\pi rad.
