Idk. Lifi uses actual light waves which are quite high up the spectrum. For sure Wi-Fi and Li-Fi are both electromagnetic waves, but light itself is a very small section of the EM spectrum. Above that wavelength you get ionizing radiation that gives you cancer and below that is harmless non-ionizing light and radio waves.
Regardless of if it's on the visual spectrum or not, it's all called light as long as it's electromagnetic radiations
Radio waves are light, gamma rays are light, gravitational waves are not, sound waves are not
