Game Introduction

How To Play

Click a green flag to start, then click ON to switch on the laser. Move the laser and the optical elements using drag 'n drop. You can rotate if you press R while single-clicking an object, and click again to stop rotating towards the mouse pointer. Set the refractive index of the fluid using the slider. You can observe total reflection. Clone the objects by single-clicking them. Exercises: 1. Build a parabolic mirror using four plane mirrors and use four lasers to shine parallel light that is reflected to a focus. All beams should meet at the same time at the focus. 2. Build a bent optical fiber using prisms and shine light in both directions.
