Term
 Laws of reflection
Definition
 1. Angle of incidence equals the angle of reflection. 2. The incident ray, the reflected ray, and the normal all lie in the same plane.
Term
 Specular Reflection
Definition
 Reflection of light off a smooth surface. (ie. still water, flat piece of aluminum foil, disco mirror ball)
Term
 Diffuse Reflection
Definition
 Reflection of light off an irregular or dull surface
Term
 *Note : Dyslexia
Definition
 Contrast of white paper and black text makes reading difficult.
Term
 Virtual Image
Definition
 An image formed by light coming from an apparent light source; light is not arriving at or coming from the actual image location.
Term
 Two observations about a plane mirror:
Definition
 1. Distance from object and mirror is exactly the same distance from image to mirror. 2. The object-image line is perpendicular to mirror surface.
Term
 SALT
Definition
 S. Size of image (same size, smaller, larger)A. Attitude (upright or inverted)L. Location of image.T. Type of image (real or virtual)
Term
 Concave (converging) mirror
Definition
 A mirror shaped like part of the surface of a sphere in which the inner surface is reflective
Term
 Convex (diverging) mirror
Definition
 A mirror shaped like part of the surface of a sphere in which the outer surface is reflective.
Term
 Centre of curvature
Definition
 The centre of the sphere whose surface has been used to make the mirror
Term
 Principal axis
Definition
 The line through the centre of curvature to the midpoint of the mirror
Term
 Vertex
Definition
 The point where the principal axis meets the mirror.
Term
 Converge
Definition
 To meet at a common point.
Term
 Focus
Definition
 The point at which light rays parallel to the principal axis converge when they are reflected off a concave mirror.
Term
 Real Image
Definition
 An image that can be seen on a screen as a result of light rays actually arriving at the image location.
Term
 Diverge
Definition
