Reflections on a Disco Ball
Ribeiro, Jair LĂșcio Prados
Physics Teacher, v54 n9 p532-533 Dec 2016
A disco ball is a spherical object covered with small plane mirrors. When light reflects on these mirrors, it is scattered in many directions, producing a novel effect. The mirror globe is usually set to rotate, creating a profusion of moving spots (Fig. 1). In this article, we present a geometrical description of the movement of these spots and an experimental activity to test the model.
