... We refer to λ as the wavelength of the wave, and ν as the frequency of the wave. For example, if ν = 5 crests per second (which is denoted 5 Hz, or simply 5 s-1), and λ = 10 cm, then from eq. (7.10), the wave spreads out at a speed v = 50 cm s-1. In the case of water waves, wave motion is easy to un ...
