Course Description: Selected experiments in physics: single component and integrated solid state electronic device characteristics and applications in electronic circuits. Use of coherent and incoherent electromagnetic waves in modern physics experiments and contemporary technology applications with transmission, absorption, diffraction, and spectroscopic measurements. Laboratory technique, data recording and analysis, communication of results through written and oral reports.

Course Objective: The objective of this course is to teach the importance of experimental physical knowledge as well as the experimental know how that goes along with it. Experimental physics lies at the very foundation of physical phenomena and every student of physics should master it before graduation. An introduction is given to experimental methods, data acquisition, analysis, as well as written and oral presentation.

Learning Outcomes: The students are expected to learn how to setup experiments, how to record reliable data, analyze their measurements, discuss their results and present their written reports in an intelligible way. They will also learn how to make effective presentations by presenting a topic of their choice on a related topic. They will gain experience in analog discrete and integrated electronic devices as well as modern physics experiments.

Teaching Method: There are two weekly face to face meetings. There are presentations and demonstrations. There is a problem session and a labor session every week.

Attendance: All students are required to attend classes, laboratory experiments, and problem sessions. Even a university approved Medical Excused Absence or Dean of Student’s Excused Absence doesn’t relieve you of this attendance requirement. Students who miss more than 1/3 of the classes (excused or unexcused) might receive an automatic F irrespective of their course average.

Labor Session: Come to the laboratory on time. You may not enter the labor session, if you are more than 15 minutes late. If you miss a laboratory experiment without an official excuse, your grade will be zero for that experiment. Come to the laboratory prepared. You should be familiar with the experiment, before you come to the laboratory. Complete the necessary preliminary work, before you come to the laboratory.

Project Report and Presentation: Each student will prepare a presentation with a related report on a state-of-the-art modern physical science and technology topic. You will make a literature search , and present your research based on the existing literature. You will find historic information about the material (i.e., who discovered it, invented it). You will find out where in the world this research is performed, as well as the related research in Turkey. Your presentation should consist of approximately 15 slides. As you will have 15 minutes, design your talk so that you will talk around one minute per page. You should spend a reasonable amount of time for preparing your presentation. All students taking this course are expected to participate in all of the presentations. Discuss your report and presentation with your instructor. He will give you tips on how to prepare a good reports and presentations. Your report should be in the scientific format. It should include an introduction, and sections on research results, their analysis, discussion, conclusion, as well as references.

Grading policy: two midterm exams (25 % each), laboratory reports (25%), and presentation with a related report on a state-of-the-art modern physical science and technology topic (25%). The dates of the exams will be announced later. Makeup exams are very reluctantly given only with a university approved medical excuse, and if given, will always be harder then the original exams. Do not plan to take makeups.

Grading policy for the laboratory: During the laboratory sessions careful laboratory practice, careful laboratory notebook keeping, and preliminary reporting in the laboratory notebook are necessary, but not sufficient conditions for the final laboratory report. 10 steps to successful reports are given under writing resources. You will submit a final laboratory report for each experiment one week after the experiment to the course instructor. There will be an instant 100% reduction for late final laboratory reports, i.e., late final laboratory reports will not be accepted.

Grading policy for the presentation: Careful literature search, excellent presentation, completely being able to answer questions are necessary, but not sufficient conditions for the presentation. 10 steps to successful presentations are given under the presentation resources. You will submit your presentation and related report by the end of the term to the course instructor. There will be an instant 100% reduction for late presentations and related reports, i.e., late presentations and related reports will not be accepted.

Laboratory Notebook: is available at the bookstore. Every student should have one square ruled A4 size laboratory notebook. Bring your laboratory notebook to all the laboratory sessions. Students without a laboratory notebook will not be admitted to the laboratory. You will record with a pen (not a pencil) the schematics, the relevant parameters, and your measurements in your laboratory notebook. You will have to date all the pages in the lab notebook during that particular experiment. After the experiment the used pages will be signed by you and the laboratory assistant.

Student Code of Conduct: Students should be familiar with the Koç University Student Code of Contact.
