The 24 pages that link to Infrared, each with the reason it gives.

• Infrared astronomyNarrower topic: It is the signal infrared astronomy detects and analyzes.

• Visible spectrumCompared with: It borders the long-wavelength edge and is perceived chiefly as heat, not color.

• Pulse oximetryRelated: A second wavelength, commonly near 940 nanometers, supports the saturation calculation.

• William HerschelBroader topic: Herschel detected this invisible radiation in 1800 by measuring temperatures beyond the red end of sunlight's spectrum.

• GrillingBroader topic: Hot coals and heating elements emit infrared energy that heats grilled food.

• Molecular vibrationRelated: Infrared photons often have energies suited to molecular vibrational transitions.

• Radio frequencyCompared with: Infrared occupies a higher-frequency region than conventional radio frequency.

• Infrared thermographyNarrower topic: Thermography detects this part of the electromagnetic spectrum.

• Radio waveCompared with: Its higher frequency and shorter wavelength distinguish it from radio waves.

• Building insulationRelated: Radiant barriers and reflective surfaces reduce some heat transfer across air spaces.

• Infrared detectorNarrower topic: Its wavelength determines which detector materials and optical components can respond.

• MicrowaveCompared with: Infrared lies immediately below microwaves in wavelength and often interacts through molecular vibrations.

• Solar radiationBroader topic: A substantial share of solar energy lies in the infrared region.

• RedCompared with: Infrared lies beyond red in wavelength but is not visible as red.

• Infrared homingNarrower topic: Infrared homing depends on detecting this part of the electromagnetic spectrum.

• LightCompared with: It can affect biological systems but lies beyond ordinary human vision.

• Luminous infrared galaxyNarrower topic: The infrared band carries the energy used to classify these galaxies.

• Terahertz radiationCompared with: Terahertz radiation borders the far-infrared region, whose boundary conventions vary.

• Eunice Newton FooteRelated: Modern accounts distinguish infrared absorption from the sunlight-driven heating Foote measured.

• SunlightBroader topic: It forms the long-wavelength portion of sunlight and contributes to radiant heating.

• ToasterRelated: Hot elements transfer much of their energy to bread as infrared radiation.

• Chemical oxygen–iodine laserNarrower topic: The device emits in the near-infrared at 1.315 micrometers.

• Infrared techniquesNarrower topic: Infrared techniques use this portion of the electromagnetic spectrum as their signal.

• Johann Wilhelm RitterCompared with: Infrared is the opposite invisible extension of visible light, discovered just before ultraviolet.
