Red light and infrared light are two types of electromagnetic radiation that are part of the visible and invisible light spectrum, respectively.
Red light is a type of visible light with a longer wavelength and lower frequency compared to other colors in the visible light spectrum. It is often used in lighting and as a signaling device, such as in stop lights. In medicine, red light therapy is used to treat various conditions such as skin issues, ألم المفاصل, and muscle soreness.
Infrared light, on the other hand, has a longer wavelength and higher frequency than red light and is not visible to the human eye. It is used in a variety of applications, such as in remote controls, thermal imaging cameras, and as a heat source in inductrial processes. In medicine, infrared light therapy is used for pain relief and to improve circulation.
Both red light and infrared light have unique properties that make them useful in various fields, from lighting and signaling to medicine and technology.
