Infrared Waves Definition. The infrared radiation or waves can be defined as waves with the wavelength in the range of 0.75 Âµm to 1 mm in the EM spectrum. Electromagnetic waves ranges from the very high wavelength (kms) to low wavelength (picometers).he infrared waves are of wavelength well below the visible region of the EM spectrum. The infrared are not visible to our eye since they are outside the narrow window of the visible frequencies. In other words, we can say that we are blind for all the spectrum except the visible spectrum.
Infrared astronomy is the branch of astronomy and astrophysics that studies astronomical objects visible in infrared radiation. The wavelength of infrared light ranges from 0.75 to 300 micrometers. Infrared falls in between visible radiation, which ranges from 380 to 750 nanometers, and submillimeter waves. Infrared astronomy began in the 1830s, a few decades after the discovery of infrared light by William Herschel in 1800. Early progress was limited, and it was not until the early 20th century that conclusive detections of astronomical objects other than the Sun and Moon were detected in infrared light.
