In engineering, “light” often means any electromagnetic radiation used to sense, communicate, inspect, heat, sterilize, or measure. A TV remote, a fiber optic link, a thermal camera, and a LiDAR unit all work with different parts of the same physical spectrum. This guide explains the electromagnetic spectrum in practical terms and shows how engineers choose the right wavelength for real products.
