We'll be the first to admit that this simulation would best be done as an actual lab ... with the actual filters and light sources. But if you don't have the equipment or if some sort of worldwide pandemic has closed down schools, then this is the next best alternative. And that's exactly how this simulation was born ... during the COVID19 global crisis. It's virus free so there's no need to keep your distance. Just launch the Interactive and start exploring.

Users are encouraged to open the Interactive and explore. For a more directed experience, The Physics Classroom has prepared a classroom-ready exercise for use with this Interactive. View Exercise.

Our Filtering Away simulation is now available with a Concept Checker. Do the simulation. Then follow it up with the Concept Checker.
