Law of Reflection
|
The angle of an incoming light source to a flat mirror equals the angle of the reflected light from the mirror. Used in Specular Reflection.
|
|
|
Spectral Reflection or Specular Reflection
|
Reflection off a smooth surface where light retains image.
|
|
|
Diffused Reflection
|
Reflection from a rough surface where light does no follow the Law of Reflection but is equally disperssed in all directions.
|
|
|
Refraction
|
The bending of light due to a change in speed usually associated with travelling between mediums.
|
|
|
Index of Refraction
|
The speed of light in a vacuum divided by the speed of light through a given medium.
|
|
|
Prism
|
A clear geometric shape used to refract light.
|
|
|
Angle Deviation
|
The change in direction of traveling light due to refraction.
|
|
|
Dispersion
|
The spreading out of wavelengths of light due to refraction. Cuase of the rainbow effect.
|
|
|
Focal Length
|
Distance from a mirror to the location where deviated light rays converge.
|
|
|
Visible Spectrum
|
Range of visible electro-magnetic spectrum between 390 nm wavelength and 750 nm wavelength.
|
|
|
Primary Colors of Light
|
Red, Green, and Blue
|
|
|
Secondary Colors of Light
|
Magenta, Cyan, and Yellow. Created by blending Primary colored light sources.
|
|
|
Speed of Electromagnetic Spectrum
|
Same as speed of light. Entire spectrum travels at 186282 miles per second.
|
|
|
Doppler Shift
|
Change of frequency in a wave due to movement of wave source.
|
|
|
Absorption Spectra
|
Darkened lines of a refracted spectrum caused by the absorption of wavelengths in elements the light has traveled through.
