Light waves are used for communication primarily through technologies such as fiber optics and wireless optical communication. In fiber optics, light signals are transmitted through thin glass or plastic fibers, allowing for high-speed data transfer over long distances with minimal loss. Additionally, visible and infrared light can be used in free-space optical communication, where data is sent through the air using modulated light beams. These methods enable fast, efficient, and high-capacity communication systems.
