Vibration

  1. Vibration refers to the rapid back-and-forth movement of an object around a central point or equilibrium. It can occur in various forms, such as mechanical vibrations in machinery, sound vibrations in air molecules, or even seismic vibrations in the Earth's crust.

2

Pitch

  1. Pitch is the perceived frequency of a sound wave, which determines how high or low it sounds to the human ear. Higher frequencies are perceived as higher pitch, while lower frequencies are perceived as lower pitch. Pitch is often measured in hertz (Hz).

3

amplitude

Amplitude refers to the maximum displacement or distance moved by a vibrating object from its central position. In the context of sound waves, it corresponds to the loudness or volume of the sound. Larger amplitudes result in louder sounds, while smaller amplitudes produce quieter sounds.

4

frequency

Frequency is the number of oscillations or cycles of a wave that occur per unit of time. In sound waves, it determines the pitch of the sound. Frequency is measured in hertz (Hz), where one hertz equals one cycle per second

5

oscillation

Oscillation refers to the repetitive back-and-forth or up-and-down motion of an object around a central point or equilibrium. It is a fundamental characteristic of waves and vibrating systems.

6

wave

A wave is a disturbance that propagates through a medium, transferring energy from one point to another without transferring matter. Waves can take various forms, such as sound waves, light waves, water waves, and seismic waves.

7

loudness

Loudness is the subjective perception of the intensity or amplitude of a sound wave. It represents how loud or soft a sound is perceived by the human ear and is influenced by the amplitude of the sound wave

8

intensity

  1. Intensity refers to the amount of energy transmitted by a wave per unit area per unit of time. In the context of sound waves, it correlates with the perceived loudness of the sound. Intensity is typically measured in watts per square meter (W/m²).

9

Wavelength

Wavelength is the distance between two consecutive points of a wave that are in phase, such as two crests or two troughs. It is often denoted by the symbol λ (lambda) and is inversely proportional to frequency. In sound waves, shorter wavelengths correspond to higher frequencies and higher pitch sounds, while longer wavelengths correspond to lower frequencies and lower pitch sounds
