Greetings to the entire academic and scientific community of steemit.

Introduction

We continue with the search of the different mobilities present in our majestic environment, this last one constitutes the space-time where humanity has carried out its life and from which it has been able to extract essential phenomena which have allowed them to extend their longevity and comfort in all their fruitful history.

We have found the phenomenon of movement in a simple or singular way both in our nature and in our daily activities, but we also identify other composite or complex mobilities based on those base phenomena such as circular, parabolic, elliptical and hyperbolic movement.

These base or fundamental mobilities are joined to the geometric places of recognized and important geometric figures which constitute the trajectories traveled by any particle, body or object when carrying out any of the base mobilities described above, and with which we have been able to continue analyzing other movements that coexist with us.

With what has been described above, we arrive at the movement that we will analyze in this article, the wave movement, which represents a type of oscillatory mobility and which is very useful both for continuing with the understanding of the movement phenomenon in a general way and for our particular or daily activities as has been pointed out in previous publications.

It is important to continue emphasizing that when we visualize a mobility that is carried out in a periodic way, and also moving back and forth to both sides of a certain equilibrium position on the same trajectory, then we are in the presence of the recognized and already analyzed oscillatory movement.

We can clearly point to a wave as a particular physical disturbance which moves or propagates through a material medium (such as air), of these waves we can mention some examples such as; seismic waves, the waves that occur on the surface of water or the known sound waves.

But we also find waves that can propagate through the vacuum like electromagnetic waves, where we can mention a very practical everyday example like radio waves, visible light and all those waves present in our electromagnetic spectrum.

The waves could be classified in several ways among them we have; according to its nature in mechanical or electromagnetic, according to its form of propagation in longitudinal or transverse, according to the direction of its propagation in traveling or stationary and according to its dimension in one-dimensional, two-dimensional or three-dimensional.

This type of undulatory phenomenon represents an area of great interest for physical science and with it for all humanity, since this characteristic is present in essential phenomena for man such as sound and light, both with an evident undulatory nature, therefore, these undulatory phenomena represent a clear means of transporting energy used continuously by our mother nature.

Mechanical waves are those that can be propagated through a certain elastic or deformable medium, with air being the clearest example of this type of propagation medium, in contrast to those waves that can also propagate through vacuum, such as the aforementioned electromagnetic waves.

Then we can affirm that the mechanical waves are those that are mobilized or propagated from a space to another through a certain material means, and in this way originating a temporary disturbance in this means of transport, emphasizing that this means is not transported or mobilized in the same way that they do this waves from a place to another.

Acoustics constitutes an important part of physical science, since it has been characterized by the analysis and study of the great phenomenon of sound, and in this way a vital ally in the deepening of any knowledge related to the wave movement and of which we are constantly witnesses when any type of sound developed in our environment reaches our ears.

It is important to emphasize that a wave movement will have its origin in a vibratory movement and this in turn represents an oscillatory movement but differs from the latter to the speed of its oscillations, the wave movement is carried out through different waves and remember that these represent a disturbance which spreads either by a material means or in the vacuum.

Around us we observe different forms of energies which are transported from one place to another thanks to the movement of some particle, body or object such as those observed in the different forms of mechanical energy, however, it is very important to be able to bear in mind that the waves originate a phenomenon of energy transfer without the particles, bodies or material objects moving.

Undulatory movement

When referring to this mobility, it is essential to talk about two important phenomena that develop such movement as light and sound, one studied in depth by physical optics and the second by acoustics, phenomena that coexist with us on a daily basis and that make undulatory movement an indispensable phenomenon for our lives.

We can express that by means of the acoustic science we have given giant steps in relation to the implemented systems as much for the registry as the reproduction of the sound, allowing us to incorporate it to important areas like the communication, the music and of equal form to the technologies of the information, among other areas.

It is always important to take into account that any type of movement will draw in its development or travel a referred trajectory as we have pointed out in each of the movements analyzed before, in the case of the wave movement we will observe this trajectory referring to such mobility as we can see in the following figure 1.

The phenomenon of the sound we can perceive it by means of the vibration of some body, these vibrations are transmitted in form of sound waves which propagate by means of the surrounding air until arriving at our ears (organ able to catch the original sound) and to be able to detect this way that a wave mobility is carried out, as we can observe in the following figure 2.

Previously we could specify that a wave represents a clear physical disturbance which is transmitted or propagated through a certain medium (such as air), these disturbances represent local variations of a certain magnitude either scalar or vectorial and that we can perceive them through our auditory sense when transported by sound waves that produce the aforementioned phenomenon of sound.

In our environment we find waves with different characteristics among which are the longitudinal or transverse waves, and when we refer to a longitudinal wave we do it when certain particles oscillate in accordance with the direction with which this wave propagates, we could express that following a behavior of a straight line as we can observe in the following figure 3.

As for the transverse waves, the particles will oscillate in a perpendicular way in relation to the direction with which a certain wave propagates, this makes that this wave moves following a curve of harmonic or periodic behavior like the one that represents the sine function, as we can verify in the following figure 4.

There are also waves like the ones we observe on the surface of a certain aquifer, where the floating particles will move up and down as well as back and forth since these waves will propagate in the form of an ellipse or slightly flattened circumference as we can see in the following figures.

As we have already observed, it is possible to find various types of waves, that is to say, wave movements, which can be classified according to various characteristics already described, which mention that depending on the nature of the wave, these can be mechanical or electromagnetic. Next, we will observe the wave movements carried out by the radiations that constitute our essential electromagnetic spectrum in the following figure 5.

Another important aspect to consider is that every wave movement will have an energy associated to that phenomenon, generally, we observe different forms of energies, which are transported from one place to another thanks to the movement of some particle, body or object as those observed in the different forms of mechanical energy, however, the waves originate a phenomenon of energy transfer without the particle body or material objects are mobilized.

Conclusion

Any type of mobility throughout our history has proven to be indispensable for our existence because both humanity and everything that surrounds us in one way or another depends on some movement to be able to develop or live as is our case, then, we can clearly express that the wave movement represents one of those essential mobilities for the whole universe, where, are immersed any kind of living species.

It is important to take into account that any wave when it propagates through a certain medium makes each of the points it reaches vibrate during its displacement, this vibration will be equivalent to that of the emitting focus, so that each of these points that vibrate will become focuses of new wave phenomena, thus generating secondary waves which will produce the vibration of the next points of the referred means of propagation, and this without the intervention of the emitting focus of the movement.

The energy transmitted without transporting matter is one of the most outstanding characteristics of wave phenomena, where the transmission of a certain physical disturbance which propagates in time through a material medium or even in vacuum can be carried out by mechanical or electromagnetic waves.

Many are the mentioned examples of these types of disturbances but the most outstanding ones, without a doubt, are represented by the recognized phenomena of sound and light, the first representing mechanical waves and the second electromagnetic waves, and therefore, these disturbances represent important forms of energy that move in a space-time through undulatory movements.

The wave movement represents a magnificent model that allows us to describe innumerable physical phenomena, the waves develop continuously around us and in most cases without us noticing their presence, however, it is possible to observe their effects, as we can observe with the radiations that constitute our wide and fundamental electromagnetic spectrum.

The mechanical waves are those that require of some physical means (like the air, liquids, among others) for their propagation and we could observe some examples in figures 2,3,4 and 5, but they are innumerable the present undulatory mobilities around us and that we have been able to implement for development of any of our daily activities.

The electromagnetic waves on the contrary of the mechanical ones can even propagate through the vacuum, this way they make it each one of the rays or present radiations in the electromagnetic spectrum as we could observe in the figure 6, in where, the main difference between these radiations is its length of waves reason why some are shorter than the other and this way one has greater amount of energy.

The vast majority of electromagnetic radiation is imperceptible to our eyes and therefore this type of mobility occurs without our eyes being able to witness such movement. However, this characteristic has not stopped us from analyzing it and also from detecting that it is a wonderful example of wave mobility, thus demonstrating that this type of phenomenon is vital for all of humanity.

Wave phenomena are everywhere accompanying us in our daily lives and thanks to the majestic field of science we understand these movements more and more, we continue to see that each type of mobility that we find in our universe has served as both a guide and a support for our exponential development, allowing us not only social welfare but also a greater possibility of existence in this majestic universe.

Until another opportunity my appreciated readers of steemit, especially to the members of the communities friends of #steemstem and #curie for which I recommend widely to be part of these exemplary projects, since they highlight the valuable work of the academy and the scientific field.
