Fluorescence

Dean S.
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.

  18. ultraviolet
    having wavelengths shorter than light but longer than X-rays

  21. wavelength
    a way of thinking or coming to mutual understanding
    http://www.conservapedia.com/Wavelength Wavelength is the distance between the crests of a wave, such as an electromagnetic wave or an ocean wave. It is given in units of length and is the reciprocal of frequency.
