Bed Prism Spectacles
Ribeiro, Jair LĂșcio Prados
Physics Teacher, v56 n1 p18-19 Jan 2018
We only became aware of the existence of bed prism spectacles when a student brought them to the classroom and asked us about how they work. The device proved to be a fertile source of curiosity among the students, and, to be properly understood, it required us to develop a comparison between reflection in a typical mirror and total internal reflection in a prism. In this article we explain the physics behind this unfamiliar device, supported by geometrical optics principles.
