concave mirror
reflects light from its inwardly curving surface, the edges of which curve toward the observer; can produce either an upright, virtual image or an inverted, real image
convex mirror
the edges curved away from the observer that reflects light from its outwardly curving surface; produces an upright, reduced, virtual image
diffuse reflection
a scattered, fuzzy reflection produced by a rough surface
focal length
distance between the focal point and the mirror or lens
focal point
point where incident light rays that are parallel to the principal axis converge after reflecting from a mirror or refracting through a lens
optical reproduction of an object formed by the combination of light rays reflected or refracted by an optical device
amount that an image is enlarged or reduced in size, relative to the object
luminous or illuminated source of light rays
plane mirror
flat, smooth surface from which light is reflected by specular reflection, producing a virtual image that is the same size as the object, has the same orientation, and is the same distance from the mirror as the object
principal axis
straight line perpendicular to the surface of a mirror or lens that divides the mirror or lens in half
real image
optical image that is formed by the converging of light rays
specular reflection
reflection produced by a smooth surface in which parallel light rays are reflected in parallel
spherical aberration
image defect of a spherical mirror or lens that does not allow parallel light rays far from the principal axis to converge at the focal point and produces an image that is fuzzy, not sharp
virtual image
image formed of diverging light rays
