Which type of light is not visible to the human eye but has applications in communication?

Infrared light is not visible to the human eye, as it falls outside the visible spectrum. While humans can see wavelengths approximately between 380 to 750 nanometers, infrared light occupies the range just beyond this, typically from about 750 nanometers to 1 millimeter. Despite being invisible, infrared light has significant applications in communication technologies. For instance, it is often used in remote controls, fiber optic communications, and short-range wireless communication systems, allowing for the transmission of data without the need for visible light. The fact that infrared wavelengths can carry information over distances without requiring a line of sight makes them valuable in various modern technologies. This ability to transmit data invisibly enhances both convenience and efficiency in communication systems.
