![]() Most of the thermal radiation released by items near room temperature is infrared. Infrared light is thought to extend from the visible spectrum’s supposed red edge between 700 nanometers to one millimeter. ![]() Consequently, it is not visible to the human eye, in contrast to occasionally visible infrared light from specially rectifier diodes with wavelengths up to 1050 nanometers (nm). So what is infrared radiation? It is a form of electromagnetic radiation (EMR), which is usually longer than the visible light wavelength. When combined, these radiations constitute the electromagnetic spectrum. Electromagnetic radiation includes all types of radiation ranked by frequency from highest to lowest, including gamma, X-rays, visible, ultraviolet, infrared, radio waves, and microwave. Infrared radiation is a spectrum of frequencies generated where atoms acquire and then release energy. However, all bodies in the cosmos release some of it. The fire and sun are two of the most prominent infrared radiation examples. Infrared radiation definition: It is a sort of radiant energy (often known as infrared light) that we experience as heat but is not visible to human eyes. Place your hand close to a hot microwave to feel infrared radiation! Define Infrared Radiation: What is an Infrared Radiation? Humans may detect infrared radiation as heat even though it cannot be seen. The article goes into great detail about infrared radiation and its characteristics and applications. Radio, and microwaves, are examples of longer infrared radiation wavelengths that are less hazardous to the human body. ![]() Short wavelength radiation like X-rays, gamma, and ultraviolet rays are high-intensity radiation that can potentially harm the human body. Infrared radiation in the electromagnetic spectrum is also classified by wavelength. All forms of radiation, from the radio waves used for telecommunications to the X-rays and MRI used in hospitals, are included in the electromagnetic spectrum. We only view a small section of the electromagnetic spectrum daily in visible light.
