|
dispersion
|
The state of being dispersed over a wide area.
|
|
|
reflected ray
|
In optics, a ray is an idealized narrow beam of light. Rays are used to model the propagation of light through an optical system
|
|
|
law of reflection
|
Specular reflection is the mirror-like reflection of light (or of other kinds of wave) from a surface
|
|
|
converging lens
|
lens such that a beam of light passing through it is brought to a point or focus
|
|
|
fiber optics
|
The use of thin flexible fibers of glass or other transparent solids to transmit light signals, chiefly for telecommunications
|
|
|
diffuse reflection
|
the reflection of light from a surface such that an incident ray is reflected at many angles rather than at just one angle as in the case of specular reflection
|
|
|
virtual image
|
An optical image formed from the apparent divergence of light rays from a point, as opposed to an image formed from their actual divergence
|
|
|
index of refraction
|
refractive index: the ratio of the velocity of light in a vacuum to that in a medium
|
|
|
incident ray
|
In optics, a ray is an idealized narrow beam of light. Rays are used to model the propagation of light through an optical system
|
|
|
focal length
|
The distance between the center of a lens or curved mirror and its focus
|
|
|
specular reflection
|
the mirror-like reflection of light from a surface, in which light from a single incoming direction is reflected into a single outgoing direction
|
|
|
normal line
|
A surface normal, or simply normal, to a flat surface is a vector that is perpendicular to that surface
