Chapter 22: Geometric Optics (Reflection and Refraction of light)


Study guide - Waves & Optics


Video (MIT) - EM waves & polarization




Topic 22.1: Wave front and rays & Topic 22.2: Reflection


Objective:
Students should understand the principles of reflection, so they can show on a diagram the directions of reflected rays.

Topic 22.3: Refraction


Objectives:
Students should understand the principles of refraction, so they can:
  1. Determine how the speed and wavelength of light change when light passes from one medium into another.
  2. Show on a diagram the directions of refracted rays.
  3. Use Snell’s Law to relate the directions of the incident ray and the refracted ray, and the indices of refraction of the media

Topic 22.4: Total internal reflection and fiber optics


Objective:
Students should understand the principles of reflection and refraction, so they can identify conditions under which total internal reflection will occur.

Topic 22.5: Dispersion


Tutorial (Univ. of California) - Dispersion of light & EM spectrum

Objective:
Students should understand dispersion and the electromagnetic spectrum, so they can:
  1. Relate a variation of index of refraction with frequency to a variation in refraction.
  2. Know the names associated with electromagnetic radiation and be able to arrange in order of increasing wavelength the following: visible light of various colors, ultraviolet light, infrared light, radio waves, x-rays, and gamma rays.
