ID Code: L3-11
Purpose: To illustrate reflection from a concave spherical mirror.
Description: A series of parallel rays are formed using a slit baffle and with concave and convex lenses. These rays are incident onto a concave spherical mirror, which focuses them to a point with some spherical aberration, as can be seen in the photograph. Number and spacing of rays are adjustable by choice of baffle and position of baffle. A baffle with sets of rays of different color can be used to draw attention to the different aberration of different sets of rays.
