Complete oscillation waves: When an oscillating body starting from a point comes back to the same point from the same direction, then it is called one complete oscillation.
Oscillation is going back and forth repetitively between two positions or states. An oscillation can be a periodic motion that repeats itself in a usual cycle, such as a sine wave, the side-to-side swing of a pendulum, or the up-and-down motion of a spring with a weight. An oscillating movement is around an equilibrium point or mean value. It is also known as a periodic motion.
One oscillation is a entire movement, whether up and down or side to side over a period of time. A complete oscillation occurs when the vibrating object moves to and fro from its original position and moves in the similar direction as its original motion.
