This document discusses different ways that light interacts with objects. It explains that light can be reflected, like when bouncing off mirrors, refracted when bending as it passes through different materials like water, and absorbed when taken in by opaque objects. Reflection forms images, refraction causes things to look bent underwater and helps us see, and absorption determines the color we observe from an object. Our eyes use the refraction of light through the lens to focus images on the retina. Telescopes also employ reflection and refraction using mirrors to observe distant objects. The document further explores how colors are part of the visible light spectrum and bend differently during refraction, forming rainbows.
