Mirrors Flashcards
convex (diverging) mirror
a mirror shaped like part of the surface of a sphere in which the outer surface is reflective
concave (converging) mirror
a mirror shaped like part of the surface of a sphere in which the inner surface is reflective
centre of curvature
the centre of the sphere whose surface has been used to make the mirror
principal axis
the line through the centre of curvature to the midpoint of the mirror
vertex
the point where the principal axis meets the mirror
converge
to meet at a common point
focus
the point at which light rays parallel to the principal axis converge when they are reflected off a concave mirror
real image
An image that can be seen on a screen as a result of light rays actually arriving at the image location
diverge
to spread apart
