Light and Our World

Mirrors & Lenses Rays are arrows that show the path of a single light wave. Ray diagrams can be used to find where images are formed by mirrors and lenses. Plane mirrors and convex mirrors produce virtual images. Concave mirrors produce both real images and virtual images. Convex lenses produce both real images and virtual images. Concave lenses produce only virtual images.

How Images Are Formed in Plane Mirrors This is a virtual image because it is right side up

The Eye The human eye has several parts, including the cornea, the pupil, the iris, the lens, and the retina. Nearsightedness and farsightedness happen when light is not focused on the retina. Both problems can be corrected with glasses or eye surgery. Color deficiency is a condition in which cones in the retina respond to the wrong colors. Eye surgery can correct some vision problems.
