I Believe It Came Straight

🪞 Where is my reflection located behind the mirror? Move an object farther away and its image stays exactly the same size—tap all four distances to test it. 💧 A coin underwater looks closer to the surface than it really is: 3/4 deep in water, 2/3 deep through glass. Can you make it look 12 cm higher? 🔍 Last is a convex lens. Beyond the focal point, it makes an upside-down image; inside it, an upright, magnified one. Put the object exactly at the focal point, though, and no image appears—follow the rays to see why. All three tell the same story: light bounces and bends, but our eyes believe it traveled straight the whole way. This app was coded too · Shall we remix it and add a concave mirror?
