displacement traveling in the sameline and with lengths as 2:1. Theform of the resultant wave dependson the phase relations, as shown by A,B and C. Fig. 179 shows one casewhen the wave lengths are as 3:1.When one wave length is not anexact multiple of the other results of still greater complexity… … Fig. 180. two trains of wave lengths as 4:3. It also represents graphicallythe addition of two simple harmonic motions with periods as 3:4.The motion swells out to a maximum and dies down to a mini-mum while one motion completes one more vibration than the other.344.
