Virtual Images: Going through the Looking Glass
Mota, Ana Rita; Lopes dos Santos, João
Physics Teacher, v55 n1 p52-53 Jan 2017
Virtual images are often introduced through a "geometric" perspective, with little conceptual or qualitative illustrations, hindering a deeper understanding of this physical concept. In this paper, we present two rather simple observations that force a critical reflection on the optical nature of a virtual image. This approach is supported by the reflect-view, a useful device in geometrical optics classes because it allows a visual confrontation between virtual images and real objects that seemingly occupy the same region of space.
