Speed links frequency and wavelength
Use v = fλ. Wave speed v is in m/s, frequency f in Hz, and wavelength λ in m. The symbol λ is the Greek letter lambda. It stands for wavelength, not a multiplication sign. In the example, f = 5 Hz and λ = 0.40 m, so v = 5 × 0.40 = 2.0 m/s. Wave speed describes the movement of the disturbance or transfer of energy, rather than the speed of a particle’s local oscillation.
