Module 3 Overview - Understanding how light propagates
Understanding how light propagates
The intent of this Module is to apply what we learned in the previous modules to understand how light reflects, refracts, and transmits through different media. Optical phenomena such as total internal reflection (TIR) and evanescent waves are discussed and explained. The module concludes with a discussion on the optical properties of metals.
Objectives
Upon completion of this week, students should be able to:
- Descibe transmission, reflection, refraction of light (various models)
- Derive the Fresnel equations for reflection and refraction amplitude
- Use Fresnel equations to calculate critical angle for TIR & Brewster's angle
- Derive a dispersion equation for metals
