The properties of spherical mirrors are discussed as we learn such terms as center of curvature, focal point, and principal axis. The properties of images formed by concave and convex mirrors are examined through ray diagrams.

-Apply the law of reflection to curved surfaces.
-Compare and contrast convex and concave mirrors conceptually and mathematically understanding and applying their similarities and differences.
-Compare and contrast real and virtual images.
-Describe the types of images that form for convex and concave mirrors when objects are beyond the center of curvature, at the center of curvature, between the center of curvature and the focal point, at the focal point, and between the focal point and the mirror.
-Define and apply the terms principal axis, focal length, and radius of curvature, conceptually and mathematically.
-Discover uses for convex and concave mirrors in real life.
center of curvature (C) - the point in the center of the imaginary sphere from which the mirror is cut.
concave mirror - a converging mirror that focuses light inward from the surface of a mirror.
convex mirror - a diverging mirror that focuses light outward from the surface of a mirror.
focal length (f) - the distance from the center of a mirror to the focal point.
focal point (F) - the point in space where parallel light rays meet after bouncing off a mirror.
principle axis - the horizontal line that connects the center of the spherical mirror with the center of the sphere of which the mirror is part.
radius of curvature (R) - the distance from the center of a mirror to the center of curvature.
real image - an image formed when light rays converge in real space.
law of reflection - this law states that the angle of reflection is equal to the angle of incidence of a light wave that bounces off a surface.
virtual image - an image that appears when light rays converge behind a mirror.
The Physics in Motion teacher toolkit provides instructions and answer keys for study questions, practice problems, labs for all seven units of study. GPB offers the teacher toolkit at no cost to Georgia educators. It will be available in September 2018. To preorder your teacher toolkit, complete and submit this form to request the teacher toolkit. You only need to submit this form one time to get materials for all seven units of study.
