We focused on flat mirrors and mirrors that have foci! Our task is to find out what happens to light that strikes a mirror such that we see an image of something in that mirror. The key is to understand how we see objects where we do. If we understand how we locate objects with our visual system, it is easy to understand how mirrors allow us to see images of objects.
An image is seen at a location from which light rays come in a way similar to how they come from the object itself. In our work we actually find the location of the image of a single point of an object. Light rays stream away from any and every point on an object that we can see. They will be seen to stream away from image points in a way similar to how they stream away from the corresponding object points. Assignment: Flat mirrors
