The word dispersion has an etymological origin in Latin “dispersionis”, which means the act of dividing, distributing or dispersing; In a general way, then, it can be described as the action of something that separates into several fragments because it has been divided. In the area of ​​mathematics this term is used to evaluate the distribution of a population and sample, which are under study, this is called “measures of variability”, by means of mathematical tricks it can be described if the variables studied are close to or far from the mean, the closer the more specific these variables will be, thus it is determined if all the cases studied have a development parameter or if they are totally different.

In the area of ​​physics, dispersion is known as the separation action of the different waves that make up a white light, these waves separate from each other according to the frequency range that each one has when it passes through a material, the different ranges are specific for a characteristic color. Depending on the material and the thickness of the elements, these can be highly or slightly dispersive. It should be noted that the dispersion effect will affect all the waves involved in radiation.

An example of dispersion is the “refractive dispersion” this results from the total separation of a white light that is the product of the association of lights in different colors, each colored light is represented by a specific wavelength and frequency; The way to observe this phenomenon is to make the light fall through a transparent material (eg prism) that will allow the colors that make it up to be observed.
