Sunlight appears white. Yet, it hides 7 colors: red, orange, yellow, green, blue, indigo, violet.
💧 Decomposition
When light passes through a drop of water or a prism, it is refracted: each color is refracted slightly differently, and they become visible as separate colors.
🌧️ Why a rainbow?
You need the sun behind you and rain in front of you. Each drop acts like a tiny prism.
🔄 What about the opposite?
A Newton disc with the 7 colors, when spun quickly, appears white: the colors recombine.
🧪 Experiment: place a glass of water on a table, a flashlight behind it, and a white sheet of paper in front: you will see a rainbow appear! Our packs
