  1. Infrared

    Infrared light is electromagnetic radiation with longer wavelengths than those of visible light, extending from the nominal red edge of the visible spectrum at 700 nanometres to 1 mm. This range of wavelengths corresponds to a frequency range of approximately 430 THz down to 300 GHz, and includes most of the thermal radiation emitted by objects near room temperature. Infrared light is emitted or absorbed by molecules when they change their rotational-vibrational movements. The existence of infrared radiation was first discovered in 1800 by astronomer William Herschel. Slightly more than half of the energy from the Sun arrives on Earth in the form of infrared radiation. The balance between absorbed and emitted infrared radiation has a critical effect on the Earth's climate. Infrared energy elicits vibrational modes in a molecule through a change in the dipole moment, making it a useful frequency range for study of these energy states for molecules of the proper symmetry. Infrared spectroscopy examines absorption and transmission of photons in the infrared energy range. Infrared light is used in industrial, scientific, and medical applications. Night-vision devices using active near-infrared illumination allow people or animals to be observed without the observer being detected. Infrared astronomy uses sensor-equipped telescopes to penetrate dusty regions of space, such as molecular clouds; detect objects such as planets, and to view highly red-shifted objects from the early days of the universe. Infrared thermal-imaging cameras are used to detect heat loss in insulated systems, to observe changing blood flow in the skin, and to detect overheating of electrical apparatus.

Examples of Infrared in a Sentence

  1. Ronald Kroger:

    It is possible that other carnivorans possess a similar infrared sense and that adds a new chapter to the story of prey-predator relationships, predator hunting strategies have to be re-evaluated and the biology of prey animals has to be revisited with body heat sensing predators in mind.

  2. February NASA:

    These clouds are so thick that even Hubble’s infrared capability could not penetrate them.

  3. Eleonora Troja:

    The very bright infrared signal from this event arguably makes it the clearest kilonova we have observed in the distant universe, i'm very much interested in how kilonova properties change with different progenitors and final remnants. As we observe more of these events, we may learn that there are many different types of kilonovae all in the same family, as is the case with the many different types of supernovae. It's so exciting to be shaping our knowledge in real time.

  4. Gene Klager:

    We are developing algorithms for infrared search and track - we have a passive way to detect and track we would then hand off the target location to a countermeasure system.

  5. February NASA:

    The red stars are either embedded or shrouded by intervening dust, these clouds are so thick that even Hubble’s infrared capability could not penetrate them.
