Frequency, Wavelength and Period extends the techniques for graphing waves begun in the lesson on Amplitude. The physical concepts of wavelength and frequency are defined here, but are not stressed. The term period is used in place of wavelength in most examples. The wave model y = A sin(Bx) is established in this lesson. A final lesson on Phase Shift realizes the full generalization y = A sin(Bx + C) + D.
