Light & Mirrors

How to play

Tap an empty square to place a mirror from the box, then tap the mirror to flip it. A ray leaves a mirror at the same angle it arrived. Filters pass only their own colour, so each lantern needs the right colour. Ibn al-Haytham showed that light travels in straight lines and that we see when it enters the eye.
