Light

Few things are more useful or essential than light, electromagnetic radiation that travels as a wave through space. This Cribsheet covers the basics of light: the electromagnetic spectrum, wave-particle duality, and how light interacts with matter. In addition, we tell you how scientists use light to study the size, age, and composition of the universe, as well as how light can help provide clean energy, faster computers, and efficient space travel.
