Apparently, this occurs when some of the electrons within certain atoms are raised to a higher energy level by the energy received and, in returning to their former level, give off a visible luminescence. This phenomenon is noted most often when invisible ultraviolet light is directed at a gem material and when the new wavelength given off is in the visible spectrum. When this happens, the invisible light produces a glow within the gemstone that we call Fluorescence. If the glow continues after the energy source is turned off, the result is called PHOSPHORESCENCE. === Examine Evidence Using A Digital Microscope" === === Apparatus: === === Results: === Based on your results, do you think that knowing more about mathematics is useful for a detective? ====== Appendix ====== USB Microsope - Veho VMS-001 (is old version) - [[http://xcsource.com/200x-8led-zoom-digital-usb-handheld-microscope-pc-endoscope-camera-for-mac-te129/|200x + 8LED Hand-held Digital Microscope]] - [[http://www.subdude-site.com/WebPages_Local/RefInfo/Computer/Linux/MicroscopesUSB/VehoVMS001/microscopeUSB_vehoVMS001.htm|gucview manual]] A list of [[http://chemistry.about.com/od/glowingprojects/ss/What-Materials-Glow-Under-a-Black-or-Ultraviolet-Light.htm#showall|materials that glow under ultra-violet]] Materials used in fishing that are [[http://midcurrent.com/flies/shining-a-light-on-uv-materials/|UV reflective]] Display [[http://users.ece.gatech.edu/~hamblen/uvminerals/Fluorescent_Mineral_Displays.htm|flourescent minerals]]
