Light is an amazing phenomenon that defies an easy description. Sometimes we describe light as a ray when we consider the straight path in which it travels; straight, that is, until it encounters an obstacle or a barrier between two different media. Sometimes we call light a wave when we study its frequency, amplitude, and interference patterns. Other times we call light a particle when we study its interaction with the electrons in an atom. When we say that light is a wave that requires no medium, or a particle that has no mass, we are using terms that defy logic. Light is so interesting it requires its own special area of physics, which we call optics.Conceptual StrandUnderstanding optics is accomplished by investigating the behavior and laws of light.Guiding QuestionHow do the properties and behavior of light relate to the basic principles of optics?
