Science Buddies: "Ask an Expert"

Hey, so, I've recently decided to build a infinity mirror, inspired by the idea on this website. I have one major question, what's the minimum/maximum distance between my pexiglass and mirror for it to work? Or is there any or does the distace affect certain things?

Hi - there isn't a set minimum/maximum distance for the mirror to work. The mirror's appearance depends on a lot of variables, light the brightness of the LEDs, the transmissivity and reflectivity of the mirror film, and the brightness of ambient light in the room. All of these variables would be great to investigate in a science project. If you wanted to test different distances between the mirror and plexiglass, you could set up an experiment with a movable front or back plate, instead of building a frame with a fixed depth. Hope that helps!
