infrared • Infrared can be obtained by a living creature or object that has the heat • Thera is can be : Green House Aspalt Sunlight
Even... • Our bodies produce infrared light from the combustion that produces energy ... let's see more
Definition of Infra-Red Infra-Red Electromagnetic Wave is a light not visible and can not break materials not transparent, that can also be caused by produce heat components, with wavelengths longer than visible light, but shorter than radio waves radiation Low Energy Waves High Energy Waves
Discovery • In 1800 William Herschel discovered “invisible light” • It’s energy with all the same characteristics as visible light, but is not sensed by the human eye • The light Herschel discovered was just beyond the red part of the spectrum. So it was named “infrared”
MICRO 0,7 microns 1000 microns Infra-Red ray included in electromagnetic wave and stay in to span frequency 300 GHZ until 40.000 GHZ and has a wavelength between 700 nm (0,7 microns) and 1 mm (1000 microns) Infra-Red ray yielded by process in hot object and molecule. Have known that by old hot object of effect of activity (vibration) atomic and molecular is in assumed to transmit heat wave in the form of infra-red ray. Therefore, infra-red ray is often referred as heat radiation.
Infra-Red Type Pursuant to Wavelength let's see more differences
Visible: dark nebula, heavily obscured by interstellar dust (“Horsehead Nebula”) Near-Infrared: dust is nearly transparent, embedded stars can be observed MidInfrared: glow from cool dust is directly observable Visible Near-Infrared Mid-Infrared
Characteristic Infra-Red • Cannot be seen by human being • Cannot penetrate items which is not transparant • Can be generated by component yielding heat • Wavelength of infra-red own adversative relation or compared to inversed with temperature. When the temperature increase, then the wavelength decrease

Virtual Laser Keyboard • The Virtual Laser Keyboard (Epic Celluon Magic Cube) is a revolutionary accessory • The only keyboard that operates in total darkness) for Iphone, Ipad, Smartphone, & Tablet PC and any device.
This tool uses the principle of infrared waves, which detects heat changes. • When we touch type button on the Virtual Laser Keyboard, the heat generated from our hands is converted into a specific code and sending through your monitor screen.
Home security systems In modern times, there are many products that offer on a home security system. One of them is a PIR (Passive Infra-Red) The passive infrared (PIR) motion detector is one of the most common sensors found in household and small business environments.
The term passive refers to the fact that the detector does not generate or radiate its own energy; it works entirely by detecting the heat energy given off by other objects.
Strictly speaking, PIR sensors do not detect motion; rather, they detect abrupt changes in temperature at a given point. • As an intruder walks in front of the sensor, the temperature at that point will rise from room temperature to body temperature, and then back again. This quick change triggers the detection.
Spitzer Space Telescope • The Spitzer Space Telescope (SST), formerly the Space Infrared Telescope Facility (SIRTF), is an infrared space observatory launched in 2003. It is the fourth and final of the NASA Great Observatories program. • the way it works is similar to a thermal detector, only the components of the tool in combination with a sophisticated telescope so that it can obtain the desired image • Here are the observations that have been made by NASA:

Infrared is electromagnetic radiation of a wavelength longer than visible light, but shorter than radio wave radiation generated by the electrons in the molecules vibrate because of heated objects and has the 1011Hz frequency up to 1014 Hz to 3 range area.. The inventor is Sir Frederick William Herschel, the astronomer United Kingdom that born in Germany. Infrared light has many benefits such as in the areas of health, electronic and communication technologies, industry, etc.
