Phenomena such as Waves, are among the most common in nature as a living and inorganic.By oscillating processes are those in which some of the exposed state of a system are recurrent.From school to all known experiments with swinging pendulum - it is an example of a simple oscillatory process.
more complex, but no less popular can be considered such a thing as a wave.Their nature is very diverse, and we can watch it on the example of the actions of many phenomena surrounding us.The most obvious, if I may say so, is a light, its distribution in various media - air, water, vacuum, chemical mixtures.
understand how interconnected Waves simply.Imagine the kind of oscillatory system, the same pendulum oscillating state, and then move it, without stopping the oscillation process, in another place, and you get a wave phenomenon.In short, the wave may be called a process in which the vibrations are moved from one place to another.
difference nature vibrations from waves can be traced on the example of their mathematical reflection.Waves of the formula which are different from each other, are expressed in this way.
Fluctuations in the simplest form, characterized by the number of vibrations parameters, their frequency and the time of committing one oscillatory cycle.The formula of the relationship of these parameters has the form: f = 1 / T, where n - the number of oscillations, T - the time period during which an oscillating process.If necessary, a more detailed description of the oscillatory phenomena are used for more options.For example, if we consider the fluctuations of the cyclic type, we will need an indicator: the phase (j) - value that shows what part of the fluctuations have occurred since the beginning of the process, the angular frequency (w), amplitude (A) showing the maximum deviationsystem from the initial state.The formula of this harmonic process then takes the form: f = A sin j, or A = f / sin j.
Given that a major factor in the differences honey waves and oscillations acts the amount of displacement in the simplest form of the wave phenomenon may reflect the formula of the form: S = A · sin ω x (t - x / v), where S - the magnitude of the wave of displacement,v - velocity of displacement (wave velocity), ω - angular frequency.
The science that deals with the study of wave-processes taken separately consider the mechanical waves and vibrations and electromagnetic .This is due to the fact that electromagnetic distributed in special environments and characterized by the fact that the propagation of the vibrational energy of the pulse is transferred without suffering the substance (of the system), which makes it swing.First of all, as exemplified herein may be varied fields: electrical, electromagnetic, radio frequency radiation of different types.
As mentioned, oscillations and waves in the theory dealt with separately, but that does not mean their isolation in nature and the technologies that have been created by man.The most striking example here may make use of the vibration-wave processes in radar.Emitting station sends wave oscillation signal having a predetermined frequency to an object that moves in a given time.It reaches of the object wave in a different time, and is reflected and comes to a receiving station (module) - for the third.That is a promise between the wave and its reception forms a time interval that characterizes the movement of an object in space.Knowing the delay time of the wave and the distance can be very accurately determine the speed of the moving object as well as its location.Moreover, the smaller the wavelength, the position determination is more accurate.
In modern technologies Waves are becoming more widely used.Well-known computer processor represents nothing other than the oscillation system, which lies several hundred million transistors committing computing operations for example oscillating in the binary system.The speed of such oscillating systems is extremely high and is measured in gigahertz.Such data can be read by any user, open the "My Computer - properties of the system."
