Chapter 23 Notes College Physics by Giambattista et al. John B. Ross, Ph.D. IUPUI Physics Dept. Geometric Optics – the study of how light rays bounce off and penetrate different materials wave fronts wavelength λ rays v f Medium – material through which light travels incident ray reflected ray θ i θ r medium 1 medium 2 Law of Reflection : θ i = θ r Whenever light travels into a new medium, its speed and wavelength changes, but its frequency remains the same.
