Introduction
In previous installments we were able to witness the implementation of several types of electromagnetic radiation imperceptible to our eyes such as the ultraviolet rays, then we met another application of this type of radiation such as the microwaves, where, we previously expressed such radiations invisible to our optical capacity, but nevertheless, of great utility in the field of technology.
Of course, it will always be necessary to emphasize that all this knowledge is due to the initial understanding of our referential fraction such as white or visible light, from there we have started and acquired the broad learning that we have today of our essential and wonderful electromagnetic spectrum.
This type of electromagnetic radiation is present in our homes, and it can originate both artificially and naturally, therefore, technology has managed to implement infrared light in well-known devices used by us at any time of our existence, where we find the well-known electronic device known as remote control, then we will show this application in the following figure 1.
Figure 1. Infrared light application (remote control)
Undoubtedly, an ingenious application that allowed us to enter fully into the era of digitization, that is, to be able to remotely manipulate any type of equipment, machine or device that we have around us and many other applications of great impact for our development, and where the road has been of great inventions.
The application of this type of radiation reaches the field of medicine such as physiotherapy, and whose application is very easy, however, it will always be necessary a due regulation to the exposure of this type of radiation to our body.
It is important to point out that infrared light or radiation, being electromagnetic in nature, logically has a place in the spectrum, as shown in figure 2 below.

Conclusion
We continue to demonstrate that everything that surrounds us has an influence on our lives in one way or another, and radiation is a clear example of this influence, and each one of us is a reliable witness of this, as we can see in the examples above.
There are many applications of electromagnetic radiation, both the visible fraction (white light) and all those that we cannot see, where we find ultraviolet light, microwaves and now infrared light.
Until another opportunity my dear and valued readers.
