Because it is periodic in space and periodic in time
periodic motion is a motion of body wich repeats itself in equal intervals of time , but a oscillatory motion is a periodic motion which is about a mean position . so all periodic motions could not be a oscillatory motion , but all oscillatory motions are periodic in nature.
because motion is moving and wave motion has waves
Both parallel and perpendicular to the motion of the wave at the same time/Perpendicular to the motion of the wave/Parallel to the motion of the wave - APEXPerpendicular to the motion of the wave.Parallel to the motion of the wave.Both parallel and pependicular to the motion of the wave at the same time.
The motion is parallel to wave direction The motion is both parallel and perpendicular to wave direction. The motion is perpendicular to wave direction.
Oscillatory motion is also called vibratory motion while periodic motion is a motion which is repeat itself after a specific interval. Periodic motion may be rotatory or vibratory.
A periodic wave done using a rope is for example a sine wave. It is the form of Simple Harmonic Motion, and traces the equation y = sin(x) where y=1 and -1 are the peaks.
Pitch is determined by the frequency of the wave; intensity (loudness) is determined by the wave's amplitude.The vibrating source moves in some kind of periodic way, and this periodic motion will have some given period. The period of a wave is the time it takes for one cycle of that wave, and the number of cycles of a given wave per unit of time is the frequency of that waveform.

A wave motion in which the vibrations of the medium are periodic rotational motions around the direction of propagation.

if a motion repeats it self after equal intervals of time it is called a periodic motion, if u understand this definition u will know that a fan is undergoing the periodic motion as if of its blades in proper words the blades of an electric fan is a periodic motion
the motion of a wave changes when it moves
In Bulk Motion, the actual object is moving along in a wave formation. In Wave Motion, only the wave is moving, not the material . Picture a 'wave' at a ball game. The people move up and down but not from seat to seat. This is Wave Motion.
If you increase the frequency of a periodic wave, the wave length decreases proportionally.
