Optics

An introduction to optics, and the optics of a plane (flat) mirror.

Video lecture on drawing ray diagrams and locating images for concave and convex mirrors. (Note: it is helpful to download the Ray Diagrams Blank pdf below.)

Video lecture on drawing ray diagrams for converging (convex) lenses and diverging (concave) lenses.

This lecture reviews how to use optic equations to calculate image distances, magnifications, and heights for mirrors and lenses. In addition, these calculations can determine if an image is real or virtual, upright or inverted, and enlarged, equal, or reduced.
