    • 4.1: Overview
      Rays, or beams of light, can travel in three ways: directly from a source, through a material, or indirectly by reflection.
    • 4.2: Reflection, Refraction, and Dispersion
      The law of reflection states that the angle of reflection equals the angle of incidence.
    • 4.3: Lenses
      Ray tracing is the technique of determining the paths light rays take; often thin lenses (the light ray bending only once) are assumed.
    • 4.4: Mirrors
      A mirror is a reflective surface that bounces off light, thus producing a real or virtual image.
