What Wikipedia says

In physics, monochromatic radiation is radiation with a single constant frequency or wavelength. For electromagnetic radiation, when that frequency is part of the visible spectrum (or near it) the term monochromatic light is often used. Monochromatic light is perceived by the human eye as a spectral color.
