Plane mirror

This simulation illustrates how the image reflected in a plane mirror looks like. The position of the object, the observer and the mirror can be changed.

Lateral inversion

An image projected onto a vertical plane mirror undergoes a so-called lateral inversion. Explain why the letters painted on the front of an ambulance are laterally inverted.


In this simulation, an image is viewed through a periscope. How many mirrors are there in a periscope? Why does lateral inversion not occur?
