Red light scatters the least because it travels in long waves. 👉 Example : Imagine throwing small stones and big balls into a pond. The small stones make ripples spread out quic...

It’s not just for looking stylish on the savannah. Scientists have studied this question for over a century, and the answers may surprise you! 🧠 1. Camouflage? Not Exactly.
