Transparent material that selectively transmits light
Coherent Light

Fluorescent light
Light generated by using phosphorus to convent ultraviolet light to visible light
Holography
Technique that produces a complete three dimensional photographic image of an object
Incandescent light
Light produced by heating a piece of metal, usually tungsten
Incoherent light
Light that can contain more than one wavelength,travel in more than one direction
Index of Refraction
Property of a material indicating how much the speed of light is reduced in the material compared to its speed in a vacuum
Linearly polarized light
Light whose magnetic field vibrates in only one direction
Mirage
Image of a distant object produced by refraction of light through air layers of different densities
Opaque
Material that absorbs or reflects all light and does not transmit any through it
Optical scanner
Device that reads intensities of reflected light and converts the information to digital signals
Pigment
Colored material used to change the color of other substances
Total Infernal Reflection
The complete reflection of a light at a boundary that occurs when light strikes an angle greater than the critical angle
Translucent
Material that transmits/scatters light, produces blurry images
Transparent
