The Physics of Vibration Vibration is defined as a rapid, repetitive motion around a central equilibrium position. As the object moves backward, it leaves a space where molecules are spread apart, creating a region of low pressure known as a rarefaction.
How Frequency Dictates the Pitch You Hear
These overtones are additional vibrations at higher frequencies that occur naturally due to the physical properties of the sound source. How Vibrations Create Waves Imagine dropping a stone into a still pond.
Sound works similarly, but in three dimensions. A vibrating object with a large amplitude pushes air molecules with more force, creating a higher pressure wave that our ears interpret as a loud sound.
How Frequency Determines the Pitch You Hear
The unique quality of a sound, known as timbre, is determined by the complex shape of the vibration wave. Amplitude refers to the maximum distance the particles in the medium move from their resting position as the wave passes.
