These words are related to Fluorescence. Fluorescent minerals are beautiful when viewed under ultraviolet light. Here is a link to some of these specimens: http://users.ece.gatech.edu/~hamblen/uvminerals/
Fluorescent minerals respond to ultraviolet light by producing a wide variety of colors in visible light. Ultraviolet light is invisible to the human eye. Only a small fraction of minerals are fluorescent. Small amounts of impurities called activators are required for many minerals to fluoresce. Different activators can produce different colors in the same mineral.

ultraviolet
http://www.conservapedia.com/Ultraviolet Ultraviolet (or UV) is electromagnetic radiation in the wavelength range of 4 to 400 nanometers, shorter wavelengths than that of visible light. The sun produces UV, which is commonly split into three bands
visible
http://www.conservapedia.com/Visible_Light The visible portion of light is that portion of the electromagnetic spectrum which is detectable by the human eye. Light from the sun appears to be white to the human eye because it contains all visible ...
