What is vibration?
What Does vibration Mean
Vibration derives from vibratĭo , a word from the Latin language. It's about the process and consequence of vibrating : making something move, oscillate, tremble, or shake. The concept can be used in different ways depending on the context .
In the field of physics , a vibration occurs when elastic waves propagate causing stress and deformation in a continuous medium. It can be said that the vibrations involve movements that are repeated around a position of equilibrium (which is the resulting position when the force is zero).
It should be noted that elastic waves are tension alterations that diffuse through an elastic medium. When an earthquake occurs , a vibration of the surface is registered as there are elastic waves (in this case called seismic waves ) that propagate.
Earthquakes, also known as earthquakes , are phenomena characterized by a strong shaking of the earth's crust that usually lasts a short time, although in some cases it leaves terrible consequences, such as the destruction of towns and cities, as well as a large number of deaths and wounded.
In music, the concept of vibration is essential, since it is thanks to this phenomenon of physics that most instruments can emit sounds; in fact, even those who do not seem to depend on it, such as those of the wind, also take advantage of it to enrich the timbre of sounds every time the air comes into contact with their walls.
Like many other species of animals, human beings have the so-called vocal cords , which are not actually cords themselves, but a set of membranous lips or folds that when vibrating produce different sounds. It all begins with inhalation, since the air is in charge of gently brushing the strings to generate said movement and maintain it for as long as necessary. Sound also causes the vibration of certain bone parts, which are known as resonators , which function as natural amplifiers.
A molecular vibration is one that affects atoms of a molecule . The vibrations can be of bending (that modify the existing angle between two bonds) or of tension (they generate a continuous alteration in the distance that exists between the atoms around the axis of the bond).
The idea of electronic vibration , on the other hand, refers to the movement made by electrons when they move through conductors and components of a system where a potential difference is applied.
In everyday language, vibration is the shaky movement that something does . A cell phone (mobile) in a state of vibration, to cite one case, is one that begins to move repeatedly when a call or message comes in.
Video games are also related to this concept, since many of the current controls include motors that vibrate when the program requires it, to intensify situations in the game such as a crash, a hit or an explosion . The first company to massify these engines was Nintendo, when in 1997 it launched an accessory for its Nintendo 64 console called Rumble Pak , which had to be inserted at the bottom of the remote and required the use of two AAA batteries to work.
It was not long before other companies copied the idea of the Japanese giant, and soon this function became a fundamental feature of video game controllers, so that many young people are unaware that Nintendo launched it. At present, on the other hand, it is no longer necessary to use batteries if the controller is connected by cable, since it receives its power directly from the console.
