Obtain an equation of a progressive wave. |
Answer» For a simple harmonic motion, displacement y = r sin(ωt + ϕ) Where r is amplitude, ω is angular velocity and ϕ is phase difference But ω = \(\frac{2\pi}{T}\) = 2πf And ϕ = \(\frac{2\pi}{T}x\) Where λ is wavelength and x is path difference. ∴ y = rsin 2π(\(\frac{t}{T}+\frac{x}{\lambda}\)) |
