Length in time of one oscillation. T = 1 / = 2 / s Phase angle. radians v g Group velocity. v g = d/dk m/s v p Phase velocity. Sometimes c is used. v p = /k m/s Beware in particular of the frequent misuse of angular frequency as frequency. I give above , the frequency, T , the period, and , the wavelength, though we dont often talk about them, as they are more familiar in everyday usage. 1...
