Class 1 - Postulates and Rules in Ray Optics

( \newcommand{\kernel}{\mathrm{null}\,}\)

Learning Objectives in this Class:

  • Understand that light travels in the form of rays in Geometrical/Ray Optics
  • Understand the physical meaning of the refractive index
  • Understand that light travels in the form of straight rays if the medium is homogeneous (i.e., refractive index = constant).
  • Estimate the reflected and refracted angles in a planar interface
  • Apply Snell’s law in one and two planar interfaces
