L3-22. Pendulum And Spherical Mirror
Purpose
Optical Illusion using concave mirror.
Equipment
Pendulum and hemispherical mirror setup as photographed.
Images
Description
A pendulum hangs at the center of curvature of a hemispherical mirror. When the pendulum is pushed so that it moves in circles around the center of curvature, the image also moves in circles around the center of curvature, but on the opposite side of the center of curvature.
