INFRARED SPECTRUM Meaning and
Definition
-
The term "infrared spectrum" refers to the portion of the electromagnetic spectrum that lies between visible light and microwaves. This segment of the spectrum is characterized by wavelengths longer than those of visible light, ranging from approximately 700 nanometers to 1 millimeter, or equivalently, frequencies between 300 gigahertz and 430 terahertz.
The infrared spectrum is divided into three main regions: near-infrared, mid-infrared, and far-infrared. Each region corresponds to a different range of wavelengths and has distinct properties and applications. Near-infrared radiation has wavelengths close to the visible light range and is often used in various electronic devices, including remote controls and optical fiber communication systems. Mid-infrared radiation has slightly longer wavelengths and is utilized in a wide range of applications such as thermal imaging, chemical and biological analysis, and remote sensing. Far-infrared radiation, with the longest wavelengths in the infrared spectrum, is commonly employed in medical imaging, astronomy, and climate research.
One of the key features of the infrared spectrum is its ability to interact with and detect heat. This property has led to its extensive use in thermal imaging devices, which capture the thermal radiation emitted by objects to create images that reveal variations in temperature. Furthermore, the infrared spectrum plays a crucial role in spectroscopy, as different molecules absorb and emit specific wavelengths within this range, allowing scientists to identify and analyze substances based on their unique absorption patterns.

Etymology of INFRARED SPECTRUM
The word "infrared" is a combination of the Latin prefix "infra", meaning "below" or "beneath", and the English word "red". This is because red light has the longest wavelength within the visible light spectrum, and infrared light has a longer wavelength than red light.
The term "spectrum" comes from the Latin word "spectrum", meaning "appearance" or "image". In the context of electromagnetic radiation, spectrum refers to the range of wavelengths or frequencies of light, with each wavelength corresponding to a specific color or band of colors.
So, combining these two terms, the etymology of "infrared spectrum" literally refers to the range of wavelengths below red light within the electromagnetic spectrum.
