Greetings again my dear friends of this prestigious platform, in other opportunities we have related to the great importance of each of the phenomena that take place in our environment, that is, around us, and one of them is the light, with the light we can observe everything around us as it manages to project images on our retina.

When talking about the projection of light on our retina I decided to make a small example of how light projects certain images from one place to another, as happens with everything that transports from our outside to our natural optical systems (eyes) specifically as already expressed the retina, let's see the following images to verify the process of the projection of any image by means of light, before this let's know the simple materials implemented.

*Roll of transparent tape.
*Transparent tape.
*Various color markers.
*Cell phone flashlight.

In the previous images they were able to appreciate how the light transports the different colors with which the transparent tape was covered to a receiving screen which in this case was the wall, highlighting that as the transparent tape represents a material medium easy to pass through we do not observe great deviation of light, we could say that there is an imperceptible refraction of these light rays, because when the refraction is considerable before our eyes we could see a phenomenon called dispersion that someone could confuse with the previous example.

La dispersión es la descomposición de la luz blanca o visible en sus colores componentes tal y como sucede con los rayos del Sol al descomponerse y generar el fenómeno que conocemos como arcoíris, si desean diferenciar el ejemplo anterior con el de la dispersión pueden realizar el siguiente ejemplo, al igual sencillo que el anterior pero podrán diferenciar entre proyección de la luz al transportar imágenes que están en su camino y la dispersión de la misma, los materiales son los siguientes.

*Pouring water container.
*Water.
*Flat mirror.
*White Sheet.

Clearly in the previous images we see how the sunlight passing through the volume of water and out takes place the wonderful phenomenon of scattering or decomposition of white light and this is what we see projected, since in this example we do not implement any color of artificial origin to see the colors observed on the screen receiving the light scattered or decomposed by the prism of water that has been made.

The projection capacity of images by means of light will depend on the material medium through which it propagates as you have been able to verify in the two previous examples, highlighting that light has provided great advances in the technological world in terms of the creation of the so-called projectors of great utility for both the educational and business field among other areas, it will always be of vital importance that we can know any kind of learning of each of the phenomena that take place around us as the essential phenomenon of light and its intrinsic phenomena.

Until another opportunity my dear friends.
