How work the infrared?

In order to understand as the infrared work, it is important to understand something on the light. The amount of energy in a light wave, is related to the wavelength: The shorter wavelengths have a greater energy. Of the visible light, the violet is the one that has more energy, and the red the one that less. Exactly next to the phantom of visible light, it is the infrared phantom.
The infrared light can be separated in three categories:

• Infrared near - more near the visible light, and it has a 1,3 wavelength that varies from the 0,7 to microns.
• Infrared near - With wavelengths that go from 1,3 to 3 microns. The previous category and this, are used in a variety of electronicses, as control of remote control is the case of them.
• Thermal infrared - the phantom of the infrared Occupies most of, and has the 30 rank from the 3 to microns.

The difference between this last and two first, are that the thermal infrared are emitted by an object instead of to be reflected by. The infrared light is emitted by an object reason why it is happening to an atomic level. The atoms are in continuous movement, and we excited if them with an external agent, they produce energy and light. In our tutorial on the technology laser we give a good explanation of how this works.Any thing that is alive, produces energy, and thus they also make some things inanimate as they can be the motors or the rockets. The power consumption produces heat. In return, the heat cause that the objects in an object ignite photons in the infrared phantom. The more it warms up it is the object, the more it cuts will be the wavelength of the infrared photon that has been released. An object that is very hot will even begin to emit photons in the visible phantom, shining in a red tone, and moving through orange, yellow, blue and finally the target.
The applications of the infrared vary in an ample rank of possibilities, that they can go from night vision, to the use in meteorology or astronomy. The military use that has occurred to the infrared mainly has been previously mentioned night vision, monitoring, location of objectives and tracking. Many devices to investigate the space, use this technology in their telescopes to penetrate in regions with cosmic dust and to detect new objects in the universe.
The border between the visible light and the infrared light is not defined of a precise form. The human eye is not too sensible to the light from 700 nm of wavelength, reason why the short frequencies do not contribute too much to common zones with common power plants. Nevertheless, particularly intense lights, like the laser, can be detected until the 780 nm, and will be perceived like red light. The line of the infrared is defined - in agreement with the standards - between 700 and 800 nm.
