The big one greeted to the community of steemit and also, to #heartstem or encouraging the content in the diversity of approach of the science for all.
For this opportunity, I want to share with you, under the doctrine of the physics, the phenomenon of the Wave. Which to observe, in matter liquidates, electrical fields, sounds and optics.
The wave. We can define like, the trasporte of energy and movement across the space, in the shape of phenomenon of perturbation, without trasportar some matter. In reference to this case, the different physical origins that provoke his appearance award very particular properties that distinguish to a few phenomena of others, for which the wave differs according to his dimensions and direction of spread; the differences as you go basis or nature of the waves they produce certain properties that characterize every wave, all the waves have a common behavior under a standard number of situations.

|Type of Wave |Nature| |---|---| |Mechanical wave| His origin or nature generally are induced, depend according to his dimension, it can be 1 dimension, 2 dimensions and 3 dimensions; since they need a material way on which to propagate | |Wave of pulse (Traveler) | The nature of this one is an average of phenomenon of pulses, one supports certain time in the space and can be transverse, longitudinal | |Acoustic waves|That they produce in a light change in the pressure of the air, of a longitudinal way, depends his level of frequency como:Frecuencias audible (20 Hz – 20 kHz), Ultrasound (> 20 kHz), Infrasonido (<20 Hz) | |Ondas electromagnetic|![electromagnetic-waves-1526374_960_720.png](https://cdn.steemitimages.com/DQmYbTwafF2d5YvG4MKgY8Y3XzqKaGzR7SYLD2YCNNKStsC/electromagnetic-waves-1526374_960_720.png)[His nature is by means of an oscillation of electrical and magnetic fields; They can propagate in the vació or in a material way](https://pixabay.com/es/ondas-electromagn%C3%A9ticas-1526374/) | Table 1 prepared one for @coolxxx
It is important to know envelopes the waves and the form that demonstrates in our environment and natives as phenomena and of that they can make use in the life, for the development of the humanity, since they are present in the daily life. |Mechanical wave|

Elements of a Wave; Comb and vale where, the Comb, it is the highest part of a wave and Vales, is the lowest top of the wave.

¿How does the length of the Wave measure itself? it is the distance understood between two comb or two vales. Wavelength is written with λ; it propagates in the way expresses itself as a function both of the position and of the time. Considerations important that it is necessary to know for his spread: The reflection of a wave, it takes place on having hit an obstacle experiences a change of direction, with the opposite sense. The refraction of one, when it experiences a directional change from one way to not initial other. The diffraction of a wave, when there happens the distortion, which expresses a wave, which at the same time prefers an obstacle, making possible changes of the order of length of the wave. Also the debate exists according to the wave geometry, since they can be; flat Waves (he persists parallel planes between if), spherical Waves (with dimensions that are circles (2D) or spheres (3D) concentric), according to his nature it can happen; Far from the source, a spherical wave can, bring near to a flat wave. An important fact, it is to know with what speed, a wave propagates it is necessary, to know the physical characteristics of the way. To know the largeness (A) it is considered to be the maximum elongation; which corresponds at the distance between the positions of balance of a point in oscillations and the positions where he is, in distantly determined, that's why it is necessary to know the characteristic of the way. ¿How is the frequency of the Wave? They are represented by the number, of times that it spends for the same point, in a unit of time. Also he adds him to him, the time passed by a particle, in realizing a finished oscillation that would be the period of the frequency. As for the speed of the spread of the waves, it is going to depend on the way of initial game, to the second half sound diferencialmente differently, for that change of rapidity happens for way that circulates, making possible a wave refraction. Speed of spread of a wave. Departing from the following thing, it is necessary to know the physical characteristics of the way. |Wave Mechanics | according to the way| |---|---| |![ it formulates 1.png](https://cdn.steemitimages.com/DQmSnb2guCKLRDvdsQbgjvzjvmx8PnBcmjaLrE34yhRdTMA/formula%201.png)For this equation he considers F = tension of the rope, like way (N), or = linear thickness, with the following unit (Kg / m) |In a rope| |![it formulates 2.png](https://cdn.steemitimages.com/DQmXHmf8kdSjBoCh4vBENiqUK8LbGNF6JtxHLa6cVUnYFYP/formula%202.png)Y = module of Young (N/m2), p = thickness of the bar (Kg/m3) His change owes to the following factors: Transverse pulse and longitudinal Pulse.|In a bar| |![it formulates 3.png](https://cdn.steemitimages.com/DQmY7MRp6qCggHd9H1vLnZuwPLRaiLZZByDzxC5SYc1vyfy/rormula%203.png)B = module of compressibility (N/m2), p = thickness of the fluid (Kg/m3)|In a surface it liquidates| |Electromagnetic wave|way |---|---| |![it formulates 4.png](https://cdn.steemitimages.com/DQmXdEZJbvi4p3cnkYBwXcR6ZXCQszo8T6T93fqSRRTcHAH/formula%204.png)n = index of refraction, c = speed of the light in the gap (3x108 m/s)|They can propagate in the vació or in a material way| |Wave acoustics applied in gases|In this occasion we see two approach| |---|---| |![it formulates 5.png](https://cdn.steemitimages.com/DQmZdk5bgwXyjy3LhXs4FpF2CF23nLp1LeUdPYXpYAvVkFq/formula%205.png)y = constant adiabática of the gas (adimensional), p = thickness of the gas, P = pressure of the gas | under the situation of thickness and pressure of the gas| |![it formulates 6.png](https://cdn.steemitimages.com/DQmSKAjbQwwgeWtLuFfCf7wxWSXNhGkp4uMPuKR2qe5dFbh/formula%206.png)T = temperature in K level of grade | under circumstance of temperature| Table 3 prepared one for @coolxxx Thanks to the level compression and of essay, new study, there have demonstrated that perturbations, which alter the geometry itself of the space - time and although it is common to represent them travelling in the gap under the approach astrophysicist, physical behavior of phenomena is waited new. Contributions important on the field or subject-matter of the waves. The gravitational waves. As indicates the Real Swedish Academy of Sciences, three big physicist, Rainer Weiss, Barry C. Barish and Kip S. Thorne, with the aopyo of Massachusetts Institute of Technology (MIT); they come from the collision of two black holes, in which this type of wave, his caught signs, September 14, 2015, and them more ironic, know how much I take in this wave comes approximately 1.300 million years, because it was demonstrated that the gravitational waves propagate at the speed of the light, it registers for the company TIED (Laser Interferometer Gravitational-Wave Observatory); and to keep on defying the mysteries of the cosmos and the universe, any report of a theory Albert Einstein predicted in his general theory of the relativity. For that one then, he was saying that he would be, a challenge to measure this wave in his theory, but already today it is a reality. As I TIE, it was possible to detect and to observe this phenomenon, by means of a pair of interferómetros laser giants, to measure a change, thousands of times smaller, that the nucleus of an atom, while the gravitational wave was exceeding the Earth. Apart from that the debate is born if this phenomenon, in the universe it has another behavior in the space - time, only it is necessary to wait for it new, I study from all this information of the gravitational waves. ![novel.png](https://cdn.steemitimages.com/DQmW6rXw9i7EtMeo9f2mgNP8fgKx24gy6jCF54STxRUiGb6/novel.png) [Source](http://www.elcultural.com/noticias/ciencia/Nobel-de-Fisica-para-los-cientificos-que-detectaron-las-ondas-gravitacionales/11290) Bibliographical source for this post: Books: Physics for student of science eingenieria for Crop Frederick General and experimental physics Written by Godemberg Physical chemistry Written by Julio De Paula image wave Physics and Chemistry 4 THAT Written by Dulce Maria Andrés Cabrerizo, Juan Luis Antón Bozal, Javier Barrio Pérez [The waves](http://www.ondes-radio.orange.com/es/acerca-de-las-ondas/que-es-una-onda) [Undulatory movement](http://www.sc.ehu.es/sbweb/fisica/ondas/MovOndulatorio.html) ![onda2.png](https://cdn.steemitimages.com/DQmbXdvLEekTq2bp8D6VitCBUCV2uaZ58pzKcJcDKbPEVop/onda2.png)
