Description

John Abbott College Science Program (200.B0) Waves Optics and Modern Physics 203-NYC-05 Course Outline At John Abbott College we acknowledge that we are on unceded Indigenous lands of the traditional territory of both the Kanien’kehá:ka, “Mohawk,” and the Anishinabeg, “Algonquin,” peoples. We are grateful for the opportunity to gather here and we thank the many generations of people who have taken care of this land and these waters. Tiohtiá:ke, Montreal, is historically known as a gathering place for diverse First Nations; thus, we recognize and deeply appreciate the historic and ongoing Indigenous connections to and presence on these lands and waters. We also recognize the contributions Métis, Inuit, and other Indigenous peoples have made in shaping and strengthening our communities. Together, as a diverse college community, we commit to building a sincere relationship with Indigenous peoples based on respect, dignity, trust, and cooperation, in the process of advancing truth and reconciliation. Due to the special circumstances of the Fall 2020 semester, the mode of delivery of this course and the evaluation plan are different from previous semesters. The course outline is subject to change based on changing guidance from health authorities. Stay safe!

Introduction Waves, Optics and Modern Physics is the third physics course and its primary purpose is to attain the Objective 00UT. Upon completion of this course the student will have the required physics prerequisites for science and science related courses at university. In this course the student is introduced to different types of oscillatory motion, both mechanical and electro-magnetic. Concepts of amplitude, frequency, wavelength and wave speed are used to describe and predict wave motions in strings and air. Interference and diffraction of light are examined by looking at light from a wave perspective. Wave-particle duality and quantum theory are explored in the section on modern physics, which includes such topics as the photoelectric effect, the Bohr atom, and matter waves. The student will also be introduced to the surprising consequences of special relativity. Students are expected to apply their math skills and fundamental physical concepts to a greater extent than in Mechanics and Electricity & Magnetism, which they have already completed. Waves and Modern Physics relates well with the other science disciplines: for example; waves with geology, optics and sound with biology, and modern physics with chemistry. Many of the topics covered lead directly to day-to-day applications such as musical instruments, lasers, holography, CDs, DVDs and Blu-Ray Discs.

Evaluation Plan The purpose of evaluation is to determine how well students meet the course objectives detailed in Appendix 1. The final mark for the course is based upon the following scheme: Assignments (weekly, minimum 9) [elements of competency 1-4]

Labs, assignments and projects must be submitted by the deadline assigned by the teacher. Failure to do so may result in a grade of zero for that assessment. Every effort is made to ensure equivalence amongst the various sections of the course. In addition to common labs and common problem sets, the final exam is both set and group-marked by all members of the faculty teaching the course. Further to this, minor adjustments to the term marks may be made at the end of the semester.

Alternative evaluation plans Should the pandemic make it impossible to hold on-campus examinations, the evaluation plan will be modified as follows. (Wear a mask, wash your hands, keep safe distances from others, we don’t want you to get sick.) Campus mid-term 1 Campus final 10% Assignments 25% Experiments 15% Mid-term 10% Test 2 40% Final exam

• • •

A computer with a reliable internet connection is necessary. A webcam and a microphone are useful for communicating with one's lab partner and instructor. A smartphone or digital camera will be necessary for laboratory experiments. Students who do not have a webcam, smartphone or digital camera must inform their teacher the first week of classes. Calculator with basic trigonometry functions is necessary for tests and the final exam which will take place at the College. [approx. $20] Students must purchase a kit with equipment for experiments. The cost of the kit is approximately 50$. Students are also expected to have a precise ruler and protractor. The textbook for the course is a selection of chapters from Open Stax: University Physics Volume 1 and Open Stax: University Physics Volume 3. The textbook is free. Go to http://departments.johnabbott.qc.ca/departments/physics/ and click on the textbook tab.

Teaching Methods The length of the course is 75 hours, divided up into 45 hours of lecture and 30 hours of laboratory work. There are two 1.5-hour lecture, and one 2-hour laboratory session per week. Classes will be delivered online; students will perform experiments at home with equipment from their kit; two summative evaluations: mid-term 1 and the final examination, will be in-person at the College. Synchronous classes will be delivered on Teams. During synchronous class and lab, students are expected to log on and participate. Students are required to adhere to the online civility and student code of conduct and must notify their teacher if they are unable to attend. Classes may be recorded by the teacher. Students who do not wish to be part of recording must inform their

In addition to Teams, Moodle and Lea, teachers may use specialized software such as LONCAPA and Turnitin for assignments. Assignments, quizzes and examinations are based on class work and applications to examples that may not be specifically covered in class, because problem solving is an integral part of the course. Students are also expected to do outside reading from the required text and work through the common problem sets. The experimental part of the course is common to all sections of the course. Experiments include the use of computers for data analysis and acquisition of data. Students are expected to produce high quality computer tables and graphs, as well as thorough discussions in their laboratory reports. Turnitin may be used to check the originality of student lab reports. Warning: This course uses lasers, intense lights and strobe lights as part of its regular teaching materials. Students are advised to follow the safety precautions outlined by the teacher during experiments. Before tests, the laboratory period may be used for a problem session where students discuss with each other and the instructor topics which may be on the test. The mid-term examination as well as the final examination will take place at the College. The mid-Term will take place on October 7-8-9 during the class’ second lecture meeting of the week. The final exam will take place during the final examination period. Details about distancing measures will be made available before the examinations. The Physics Department encourages evidence-based pedagogical innovation and participates in physics education research projects. Some sections may use active learning instructional strategies. See your instructor’s addendum for details specific to your section.
