This is an ancient question, something we encounter everyday from the moment we open our eyes, from the first moment weÕre born. The essence of light is that it is a form of energy. Being a form of energy means that it follows one of the major laws of physics, mainly the law of conservation of energy. This law states that energy is never created nor destroyed. Energy is converted from one form to another. Physics has two models to describe the behavior of light. There is the wave model and the particle model. They are both equally valid, and the details are not too important in our treatment of light, although for our purposes the particle model is the predominant model used in computer graphics.
