As you may know, the visible light range ROYGBIV (Red, Orange, Yellow, Green, Blue, Indigo, Violet) is only one fraction of the electromagnetic spectrum, comprising EM radiation in a frequency range of approximately 430–750 terahertz. Once you start to get lower or higher frequency than that, you enter a realm that is invisible to the human eye, with different wavelengths being produced in very distinct ways and having unique effects on matter. The EM radiation most immediately lower-frequency than visible light is called infrared, and the EM radiation most immediately higher-frequency is called ultraviolet. Starting at 11 AM EDT on 5/23 and going for 24 hours, you’ll have a chance to duke it out on Eyewire for your favorite of the two!
Infrared
Wave frequency ranges from 300 gigahertz to 430 terahertz, pushing at the very edge of visible red light, hence the name. In layperson’s terms, infrared radiation is usually created by objects’ heat, which i...Infrared, Visible, and Ultraviolet Radiation - Sliney | 合法醫療器材資訊網
