Term
 Concave Mirror
Definition
 curved mirror for which the center is behind the outer edges; the mirrored surface is cured inward
Term
 Convex mirror
Definition
 curved morror for which the center protrudes out beyond the outer edges; the mirrored surface is curved outward
Term
 Vertex
Definition
 the point at which the principal axis meets a mirror
Term
 Focal Point
Definition
 of a mirror or lens is the point at which converging light rays meet or form which light rays diverge
Term
 Law of Reflection
Definition
 the angle of reflection of a light is equal to the angle of incidence
Term
 Angle of reflection
Definition
 the angle between the reflected ray and the normal
Term
 Angle of refraction
Definition
 the angle between normal and the refracted ray
Term
 Angle of incidence
Definition
 the angle between the incident ray and the normal
Term
 Reflected ray
Definition
 The ray leaving a reflecting surface after an imcoming ray has struck the surface
Term
 Refraceted ray
Definition
 a ray that describes the direction of light after passing from one medium to another of different density
Term
 Principal axis
Definition
 a line that is normal,or perpendicular, to the center of a mirror or lens
Term
 Plane mirror
Definition
 a flat, smooth mirror, or reflecting surface
Term
 Incident ray
Definition
 a ray that strikes a reflacting or refracting surface
Term
 Normal
Definition
 an imaginary line perpendicular toa surface such as a mirror or lens
Term
 Amplitude
Definition
 the distance between the highest point on a wave(crest)orthe distance between the lowest point on a wave(trough)
Term
 Crest
Definition
 the highest part of the wave
Term
 energy
Definition
 the capacity to apply force over a distance
Term
 Trough
Definition
 the lowest part of a wave
Term
 Refaction
Definition
 the changing of direction or bending of lights or other type of wave when travelling from one medium to another medium having a different density
Term
 Reflection
Definition
 the process in which light or another type of wave interacts with a surface and is sent back from the surface
Term
 Pythagoras
Definition
 a greek philosopher who belived that light beams were made up of tiny particles
Term
 Telescope
Definition
 a device used to magnify distance objects, composed of a comdination of lenses or mirrors
