Light usually implies 'visible light', which means this article is really already covered. For example this is a quote from 'Wikipedia Light' (
light):
- Visible light is the portion of the electromagnetic spectrum between wavelengths of about 400 nm and 800 nm (in air). The different wavelength mixtures are interpreted by our brain as colors, ranging from red at the lower frequency to violet at the highest.
- On the other hand, it's common to say "Ultraviolet light" or "Infrared light".
The same article (
light) then says:
- The term light can also refer generally to electromagnetic radiation, e.g. ultraviolet light or infrared light. The study of light and the interaction of light and matter is termed optics.
