Chapter 23. Ray Optics

Chapter 23. Ray Optics. Our everyday experience that light travels in straight lines is the basis of the ray model of light. Ray optics apply to a variety of situations, including mirrors, lenses, and shiny spoons. Chapter Goal: To understand and apply the ray model of light.

Ray Tracing

Ray Tracing. A radio signal will typically encounter multiple objects and will be reflected, diffracted, or scattered These are called multipath signal components. Represent wavefronts as simple particle Geometry determines received signal from each signal component

Chapter 23

Chapter 23. Ray Optics (The Ray Model of Light & Reflection). 23.1: The Ray Model of Light. The ray model is valid as long as any apertures through which the light passes are very wide compared to the wavelength of light.

5.1 The Ray Model of Light

5.1 The Ray Model of Light. Some properties of light are best described by considering light as a wave. Other properties of light are best described by considering light as a particle. The ray model of light uses a straight line, or ray, to show the direction the light wave is traveling.
