Concept: The motions that incorporate vibration, or the to-and-fro movement at a quicker pace, will be used as instances of vibratory motion. Because the oscillatory motion is represented by a slower to and from motion.
A particle oscillates around a fixed point; this form of motion is known as vibratory motion.
The only distinction between oscillatory motion and vibratory motion is that the former is used to describe motion that involves a particle moving faster around a fixed point or oscillating at a low to medium frequency. The latter is used to describe motion that involves a particle moving slower around a fixed point or oscillating at a lower to medium frequency.
Following are some instances of vibratory motion.
An actual example would be a tuning fork that is vibrating.
the phone's vibration when it rings.
the sound made when a stick struck the drum's batter head.
the shaking of a car's components as the engine fires up.
the eardrum's trembling in response to sound.
As soon as the generator is turned on, it begins to vibrate.
As soon as the mixer is turned on, the grinder jar begins to shake.
∴ The vibratory motion is the back and forth movement of particles around a fixed point.
Hence, the correct answer is option 4.
