Mirror and Lens Videos from Khan Academy
Tutorial videos accessible on this site support concepts learned in the classroom. The relevant links to mirrors and lenses are found in the Physics section of this site.
Four videos (Virtual Image, Parabolic Mirrors and Real Images, Parabolic Mirrors 2, Convex Parabolic Mirrors) show how to construct ray diagrams for images formed by mirrors. Three other videos demonstrate ray diagram construction for lenses (Convex Lenses, Convex Lens Examples, Concave Lenses). Two other videos derive and apply the thin lens/mirror equation and magnification (Object Image and Focal Distance Relationship (Proof of Formula), Object Image Height and Distance Relationship).
