|
Dispersion
|
describes the variation in the refractive indices of different colors of light.
|
|
|
Reflected Ray
|
a light ray that bounces off a surface.
|
|
|
Law of Reflection
|
states that when a light ray reflects off a surface, the angle of incidence is equal to the angle of reflection
|
|
|
Converging Lens
|
a convex lens that bends light rays as they come together
|
|
|
Fiber Optics
|
thin glass fibers that use total internal reflection to carry light
|
|
|
Diffuse Reflection
|
the scattering of light into many directions off a non-shiny surface
|
|
|
Virtual Image
|
forms when rays of light appear to be coming together, but do not actually come together; a virtual image cannot be projected on a screen
|
|
|
Index of Refraction
|
a ration that gives a measure of a material's ability to bend light
|
|
|
Incident Ray
|
A light ray that strikes a surface
|
|
|
Focal Length
|
the distance from the center of a lens to the focal point
|
|
|
Specular Reflection
|
reflection that occurs off smooth surfaces; the light rays are not scattered, and the reflected image is undistorted
|
|
|
Normal Line
|
An imaginary line drawn perpendicular to the surface of a mirror
