Chapter 35: Nature of Light and Laws of Geometric Optics

Chapter 35: Nature of Light and Laws of Geometric Optics 35.1 The Nature of Light Before the beginning of the nineteenth century, light was considered to be a stream of particles The particles were either emitted by the object being viewed or emanated from the eyes of the viewer
