Lecture Description
Fundamentals of Physics, II (PHYS 201) Geometric optics is discussed as an approximation to wave theory when the wavelength is very small compared to other lengths in the problem (such as the size of openings). Many results of geometric optics involving reflection, refraction (mirrors and lenses) are derived in a unified way using Fermat's Principle of Least Time. 00:00 - Chapter 1. Light as an Electromagnetic Phenomenon 07:17 - Chapter 2. Review of Geometrical (Classical) Optics 21:50 - Chapter 3. Fermat's Principle of Least Time and its Corollaries Complete course materials are available at the Open Yale Courses website: http://open.yale.edu/courses This course was recorded in Spring 2010.
Course Description
This is a continuation of Fundamentals of Physics, I (PHYS 200), the introductory course on the principles and methods of physics for students who have good preparation in physics and mathematics. This course covers electricity, magnetism, optics and quantum mechanics. Course Structure: 75 minute lectures, twice per week
