Incandescence
the emission of light due to an objects temperature.
Phosphorescence
a slow emission of absorbed electromagnet energy, similar to fluorescence.
Ray
a model of light in which the endpoint represents the lights source and the light travels in one direction.
light rays
Diverging lens: a lens that causes ________ to separate (diverge); also known as concave lens.
Chemiluminescence
the emission of light energy from chemical reactions.
Fluorescence
the emission of light after an object absorbs high- energy electromagnetic waves.
Diffuse reflection
the reflection off a rough or uneven surface that reflects light rays in all directions.
Concave mirror
a curved mirror with the reflective side on the inside of the curve.
Lens
a disk of transparent material that refracts light to produce a real or virtual image.
Convex mirror
a curved mirror with the reflective side on the outside of the curve.
converging lens
a lens that causes light rays to come together (converge); also known as convex lens
luminous object
an object that is producing visible light
illuminated object
an object that is visible because it reflects light from an external source

transparent material
a material through which light passes without scattering, transmitting a clear image
translucent material
a material through which light passes but the light is scatter and does not transmit a clear image
opaque material
a material through which visible light cannot pass
primary colors
one of the three colors (red, blue, and green) of visible light that the human eye can sense'; mixed to produce
secondary colors
a color of light that is produced when primary colors are mixed
additive color
a color that is produced by combining the wavelengths of different colors
subtractive color
a color that forms because of pigments absorbing some wavelengths of light that strike an object
diffuse reflection
the reflection off a rough or uneven surface that reflects light rays in all directions
reflected ray
the ray that bounces off a surface
incident ray
a light ray approaching a surface; an incoming ray
law of reflection
the law that states that when a light ray reflects off a surface, the angle of the incident ray equals the angle of the reflected ray
plane mirror
a flat mirror
virtual image
an image produced by diverging rays
real image
an image that forms at the point where converging rays of light
concave mirror
a curved mirror with the reflective side on the inside of the curve
focal point
the point on an optical axel at which all reflected or refracted light rays from incident rays that are parallel to the optical axis converge
focal length
the distance from the center of a ens or mirror to its focal point
convex mirror
a curved mirror with the reflective side on the outside of the curve
index of refraction
the ratio of the speed of light in a vacuum to the speed if light in the medium
