Assignments and Activities
 Homework: Several homework sets will be assigned throughout the semester. Solving the homework problems is crucial for success in the course. The problems in the tests will relate to the concepts covered in the homework problems and in the worked out problems in the class and in the textbook. Homework assignments have to be submitted within the deadline.
 Short Quizzes: Several synchronous short quizzes (15 minutes each) will be given, commonly one after completing a major topic.
 Tests: Two synchronous in-class tests will be given. Each test will count 20% towards the final grade. Final will be synchronous, cumulative and carry 30% weight.
Please note, the CUNY Administration advises us that the courses could require the use of online proctoring. Necessary preparation may be required when they finalize the online proctoring system(s) to be used.
Course Organization
 Course Materials: Materials covered in the course are organized into two broad areas: Physical Optics and Modern Physics. Approximately 50% time will be devoted to topics belonging to these areas.
 Attendance: Class sessions will focus on discussion of concepts, derivation of key formulae, as well as, problem solving. Regular attendance, on-time arrival, and participation in entire class sessions are required. Absence in a test without prior permission, or unavoidable circumstances (such as, sickness, emergency, etc.) will result in a score of “0” for the test.
 Study Tips: To derive maximum benefit from lectures, please read the material indicated in the schedule before the class. To be up to date, please go through the lecture notes, textbook, and rewrite your lecture notes before the next class. To develop comprehension of the materials and to be able to use those, solve the homework problems, and engage your classmates and instructor in discussions. While individual efforts may vary, on the average expect to spend 6-10 hours per week, studying, discussing and solving problems, in addition to the time spent in lecture.
 Communication and Access: Black Board (BB), Zoom and E-mail will be our principal modes of communication and interaction. You may want to check that your Black Board access is in place. If you need any support, please contact CCNY Black Board Support by phone at (212) 650-6990 or/and by email at bbsupport@ccny.cuny.edu .
You may also want to brush up your BB skills by visiting and consulting the site https://www.ccny.cuny.edu/it/blackboardguides
 Technology Requirement: You will need a computer with reasonable audio and video capabilities and a dependable Internet access to take online courses. If you do not have your own computer and need to borrow one, please contact CCNY Laptop Loaner Program by phone at (212) 650-5480 or/and e-mail at: iMEDIA@ccny.cuny.edu .
