What is light? Light is a form of electromagnetic radiation that our eyes can detect. It's made up of tiny particles called photons. These photons have both wave-like and particle-like properties, a duality that's one of the intriguing aspects of light. Now, light moves incredibly fast, about 186,282 miles per second (or 299,792 kilometers per second). That's why it seems to reach us almost instantly. Colors come into play when we talk about light. Different colors correspond to different wavelengths of light. When you see a rainbow, you're witnessing the separation of these wavelengths. Light interacts with matter in various ways. It can reflect off surfaces, like a mirror, or refract, bending as it passes through different materials, like glass. Ever wonder why a straw looks bent in a glass of water? That's light bending due to a process called refraction. In a nutshell, light is this incredible blend of waves and particles, speeding through space, bringing us col...
