Department of Physics and Astronomy PHY 308 Principles of Optics Spring 1997 I. The Course Instructor: Kwok-Wai Ng Office CP 385 Telephone 7-1782 Office hour: Monday 10:00-11:00 a.m. Time: Monday, Wednesday, and Friday 1:00-1:50 p.m. Place: CP 183 Text book: Introduction to Optics, 2nd edition F. L. Pedrotti, S. J., and L. S. Pedrotti Published by Prentice Hall in 1993. II. Goal Wave motion has been an important phenomenon in Physics. In PHY 231 and PHY 232 we learnt about sound waves and electromagnetic waves. We have used the mathematical formulation for wave motion to describe simple harmonic motion, and to analyze ac circuits. Wave mechanics forms the foundation of quantum physics, and many new phenomena cannot be explained without the notion of waves. In this course we will provide the first comprehensive account on this important concept. However, we will limit ourselves on one type of waves, that is visible light as an electromagnetic wave. We will learn about the mathematical descriptions of waves, the wave equation, the use of complex numbers, and the Fourier transformation. We will study different properties of wave motion, with optical phenomena as examples. The course will begin with geometric optics, in which the wave characteristic of visible light is not obvious because the wavelength is assumed to be very small in comparison with the dimension of the system. We will then go through the mathematics of waves and introduce different phenomena due to the wave characteristic of light (physical optics). We will also discuss the electromagnetic origin of visible light and its interaction with materials. III. Grading Policy There will be about one homework set of six to seven problems every week. The homework is due on the dates indicated. Late homework will not be accepted. It should be noted that the answers to most problems can be found in the back of the text. The solutions handed in, however, should be complete and comprehensive. They should also be neat and legible, with the solutions presented in an ordered and logical fashion. Solutions not satisfying these criteria will suffer a severe reduction in grade. The homework will count for 30% of your total grade. Each homework problem will be weighted equally. There will be two hourly tests, listed in the class schedule below. Each test will contribute 20% towards your total grade. This component will therefore constitute 40% of the final grade. The tests will cover all the material covered prior to their schedule dates, but after the previous test. This material will include what is covered in the readings, in the lectures, and in the assigned homework. There will be a two hour final examination that will be comprehensive, covering all materials studied in this course this semester. This final examination will constitute 30% of your final grade. The examination will take place on Thursday, May 8, from 3:30 to 5:30 pm in CP 183. In general, all tests and the final examination will be closed book. You will need to bring your own scientific calculator, and your own writing tools. You are not allowed to use any programs stored in the memory of the calculator.
