You can stop and continue the simulation by using the "Pause / Resume" button.The Interactive consists of two parts. Part 1 is titled How do light rays reflect? This part introduces the law of reflection and addresses the manner in which light reflects off a plane mirror. Part 2 is titled How do images form in plane (flat) mirrors? This part investigates the interaction between light from the object and the observer's eye.
