Progressive Wave Equation

In a sine wave, minimum distance between 22 particles always having same speed is

Show answer and solution

Answer: (a)

  1. Particle speed =Aω∣cos⁡ϕ∣= A\omega|\cos\phi|, so two particles always have the same speed if their phases differ by π\pi.
  2. Phase difference π\pi corresponds to path difference λ2π×π=λ2\frac{\lambda}{2\pi} \times \pi = \frac{\lambda}{2}.
  3. So the answer is (a) λ2\frac{\lambda}{2}.
