a surface that reflects light rays
Mirror
an optical device for bending light rays
Lens
a single dot that forms part of an image made of many dots
Pixel
the smallest possible amount of light, in the form of a wave bundle
Photon
the sensation created by the different energies of light falling on your eye
Color
a form of electromagnetic energy that makes things visible
Light
the process of bending while crossing a surface; light bends passing from air into water or back
Refraction
a process that makes light directly from electricity
Fluorescence
a lens that bends exiting light rays outward, away from the focal point
Diverging lens
a process that makes light with heat
Incandescence
light containing an equal mix of all colors
White Light
the entire range of electromagnetic waves, including all possible frequencies
Electromagnetic Spectrum
they subtractive color process using cyan, magenta, yellow, and black to create colors in reflected light
CMYK
a lens that bends exiting light rays towards the focal point
Converging lens
the process of light rays bouncing off a surface
Reflection
a model for tricking the eye into seeing almost any color by mixing proportions of red, green, and blue light
RGB color model
allows light rays to pass through without scattering
Transparent
a glass shape with flat, polished surfaces that can both bend and reflect light
Prism
allows light rays through but scatters them in all directions
Translucent
a unit of length equal to 1 billionth of a meter
Nanometer
a wave of electricity and magnetism that travels at the speed of light
Electromagnetic Wave
“shiny” surface reflection, where each incident ray produces only one reflected rays
Specular Reflection
an imaginary line that represents a beam of light
Light Ray
“dull” surface reflection, where each incident ray produces many scattered rays
Diffuse reflection
a number that measures how much a material is able to bend light
Index of Refraction
