Introduction
The Concave/convex Mirror Accessory is designed for use
with a PASCO optics system such as OS-8515C, or an optics
bench such as OS-8541 or OS-8508. It consists of a dou-
ble-sided curved mirror and a semicircular half-screen.
The mirror is concave on one side and convex on the other
side. Both sides have the same radius of curvature.
The half-screen is designed for showing an image formed by
the concave side of the mirror. The screen can be rotated in its
mount so that its edge is vertical or horizontal.
Demonstration
Position the mirror and half-screen as
illustrated (right) with the concave
side toward the screen. You can
mount the components on an optics
bench, place them on a tabletop, or
simply hold them. Adjust the dis-
tance between the mirror and screen
to form the image of a bright object
such as a light source, lamp, or win-
dow.
