infrared[in′frə red′, in′frə red′]
- The definition of infrared is light rays which are longer than light but shorter than radio waves.
- Electromagnetic radiation with a wavelength between .7 and 300 micrometres is an example of infrared.
- A camera that can detect these wavelengths is an example of a camera that reads infrared.
- Of or relating to electromagnetic radiation between microwaves and red visible light in the electromagnetic spectrum, having frequencies between 300 gigahertz and 400 terahertz and wavelengths between 1 millimeter and 750 nanometers.
- Generating, using, or sensitive to infrared radiation.
- Having the wavelength in the infrared.
- infrared light
- infrared waves
- infrared radiation
- In the infrared spectrum.
infrared - Computer Definition
An invisible band of radiation at the lower end of the visible light spectrum. With wavelengths from 750 nm to 1 mm, infrared starts at the end of the microwave spectrum and ends at the beginning of visible light. Infrared transmission typically requires an unobstructed line of sight between transmitter and receiver. Widely used in most audio and video remote controls, infrared transmission is also used for wireless connections between computer devices (see IrDA) and a variety of detectors (see IR detector). Infrared Can Be Anything Below Red Infrared means "below red," and red frequencies are at the bottom of visible light. Therefore, infrared may refer to any type of invisible electromagnetic radiation below visible light, including AM, FM and TV. See infrared imaging, infrared wavelengths, IR remote control and IRED.
