Let’s uncover the physics behind rainbows. 🌧️🌈 How do they form? 1. Sunlight enters a raindrop and slows down, bending (refraction). 2. Inside, light reflects off the back of the raindrop. 3. As it exits, it refracts again, splitting into its different colours (dispersion). Why do you see an arc? Because only light at a specific angle (~42°) reaches your eyes as a rainbow. 🌈 Nature is full of hidden science and beauty. | Fadhel Mahdi
