The term "full spectrum" refers to a complete range or variety of something. It can be used in various contexts, but generally implies that everything from one end of the spectrum to another is included and accounted for. For example, when referring to light, full spectrum means that it includes all colors of the visible spectrum - red, orange, yellow, green, blue, indigo, and violet - rather than just a specific portion or narrow range of wavelengths. In other contexts, such as nutrition, "full spectrum" may refer to a product that contains an entire range of vitamins, minerals, and other essential nutrients.
