Vibration
Vibration refers to the rapid back-and-forth movement of an object around a central point. In physical acoustics, this movement produces sound waves: when an object like a guitar string moves, it pushes against the surrounding air, creating pressure waves. These waves travel through the air to our ears, where they are perceived as sound. Vibration can occur in solid objects, liquids, or gases, and is essential for various phenomena, including music and speech. The frequency of vibration determines the pitch of the sound, while its amplitude affects the loudness.

Vibration refers to the rhythmic motion of an object back and forth around a central point. It occurs when energy is applied to a material, causing it to oscillate. This can be seen in everyday examples, such as the strings of a guitar when plucked or the sound of a phone vibrating. Vibration is a fundamental concept in physics and engineering, affecting how objects behave under forces, contributing to sound production, and influencing the design of structures and machines to ensure they can withstand such movements without damage.
