PHYS-321 “Optics” FALL 2016 CRN: 81373 Instructor: Dr. Alan Bristow Office: White Hall 439 Email: [email protected] Tel: (304) 293-5193 Class hours: MWF 11:30am -12:20 pm Class location: White Hall G4 Office hours: By appointments Course description: Classical optics encompasses the behavior of light as it propagates and interacts with matter. This subject has ancient roots, but is extremely relevant to modern science and technology. This course explores the foundations of geometric and physical optics. A full list of topics is shown on page 3. Course objectives: Upon completion of this course, students will have developed understanding of fundamental phenomena in classical optics and the mathematical skills needed to solve problems in geometrical and physical optics. Pre-requisites: PHYS111, PHYS112 and MATH261. Also, PHYS211 is useful. Textbooks: Required: Optics (4e), Eugene Hecht, Addison-Wesley (Pearson) 2001 [ISBN-10: 0805385665, ISBN-13: 978-0805385663] Reference: facebook group WVU-PHYS321-01-Optics [ https://www.facebook.com/groups/635315129825982/ ] Homework: Short problem sets will be assigned reguarly to reinforce material discussed in the class. To receive full credit assignments must be turned in on the due dates. Please be neat, show approach to your solutions and follow all instructions. Homework problems that are not in the required text will be provided as handouts during class or via e-mail. Grading, examinations and dates: Assignment Discussion Homework MidTerm 1 MidTerm 2 MidTerm 3 Final Exam Distribution of final grade 6% 25% 13% 13% 13% 30% Date In Class Regularly 9/19 (in-class) 10/14 (in-class) 11/9 (in-class) 12/13, 11 am-1 pm All schedules are subject to revision; the changes may be verbally announced in class. Students are responsible for obtaining all information given in class, even if the student is absent. Midterm exams will test material relevant to that section of course being taught at the time. The final exam will cover the entire course. 1 PHYS-321 “Optics” FALL 2016 CRN: 81373 Academic misconduct: Appropriate disciplinary action, potentially including failing the student, will be taken in the event of plagiarism, dishonesty, or other academic misconduct. Calculators will be permitted in all tests and exams. For exams, cheating is unethical and is unacceptable. Signed honor statements will be required for any take home test/exams choose to give by the instructor. Grading policy: Examinations, tests and homework will be graded on the conveyed understanding of the materials under test. Students will receive number grades for each problem: “0” for not attempted, “1” for unsatisfactory, “2” for satisfactory, and “3” for exemplary. Final letter grades will be determined from the total points acquired for each problem using the weighting presented in the table above. Attendance policy: Attendance is mandatory. Please inform the instructor in advance if you will miss class. Consistent with WVU guidelines, students absent from regularly scheduled examinations because of authorized University activities will have the opportunity to take them at an alternate time. Make-up exams for absences due to any other reason will be at the discretion of the instructor and are not guaranteed. Add/drop policy: Students must properly withdraw from a course. Simply not attending a class does not constitute a formal withdrawal. Details for adding and dropping a class can be found at http://online.wvu.edu/Registration/dropAdd.php. Statement of non-discrimination: West Virginia University is committed to social justice. As the instructor of the course, I expect to maintain a positive learning environment based upon communication and mutual respect. Any suggestions as to how to further such a positive and open environment in this class will be appreciated and given serious consideration. The university does not discriminate on the basis of race, sex, age, disability, religion, sexual orientation, color, or national origin. If you are a person with a disability and anticipate needing any type of accommodation in order to participate in this class. Please advise me and make appropriate arrangement with Disability Services (293-6700). The instructor reserves the right to modify this syllabus as deemed necessary any time during the semester. Emendations to the syllabus will be discussed with students during a class period. Students are responsible for information given in class. There may be also details about PHYS 321 uncovered in this syllabus. Do not assume something just because it is not specified in the syllabus. If you are unsure about anything related to the rules guiding this course, consult with the instructor ahead of time. 2 PHYS-321 “Optics” FALL 2016 CRN: 81373 Physics 321 Topics: 5.
