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. As students have already completed Mechanics and Electricity & Magnetism, they are expected to apply, to a greater extent, their math skills and fundamental physical concepts. 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:

Reminder: No electronic devices, other than a basic calculator with trig and scientific functions, are permitted on the final exam. This includes graphical / programmable calculators and electronic translators 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. NOTE: 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.

Required Texts and Materials • • • •

Open Stax: University Physics Volume 1 and Open Stax: University Physics Volume 3 (freely available online or in print for ~$15), go to http://departments.johnabbott.qc.ca/departments/physics/ see textbook Physics NYC Laboratory Manual (Labs & Problem Sets): Printed by JAC Bookstore [approx. $10] Calculator with basic trigonometry functions [approx. $20]

There may be an additional cost for a package of material prepared by an individual instructor for his/her section(s) (printed by JAC Bookstore) [approx. $20, varies section-to-section]

Teaching Methods The length of the course is 75 hours, divided up into 45 hours in the classroom and 30 hours in the laboratory. There are two 1.5-hour classes, and one 2-hour laboratory session per week. (EN sections have one additional 1-hr class). The Physics Department encourages evidence-based pedagogical innovation and participates in physics education research projects. Some sections may be offered in a blended learning format where up to 40% of face-to-face time may be replaced with online activities. Some sections may use active learning instructional strategies. See your instructor’s addendum for details specific to your section. Work in the laboratory includes the use of computers for data analysis and acquisition of data. Computers are available for analysis of data during the laboratory and the learning center. The laboratories are common to all sections of the course. Students are expected to produce high quality computer tables and graphs, as well as thorough conclusions in their laboratory 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 in the lab manual and by the teacher during laboratory 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. Problem solving is an integral part of the course and the assignments (and/or quizzes) are based on class work and applications to examples that may not be specifically covered in class. The student is also expected to do outside reading from the required text and work through the common problem sets at the back of the lab manual.

Departmental Attendance Policy • Attendance at lab periods is compulsory. If a student is absent from 3 or more labs without a valid reason he or she may receive a failing grade for the course. • A valid medical note is required if an evaluation session is missed due to illness.

Policy No. 7 – IPESA, Institutional Policy on the Evaluation of Student Achievement: http://johnabbott.qc.ca/ipesa □ Changes to Evaluation Plan in Course Outline (Article 5.3) Changes require documented unanimous consent from regularly attending students and approval by the department and the program dean. □ Religious Holidays (Article 3.2.13 and 4.1.6) Students who wish to miss classes in order to observe religious holidays must inform their teacher of their intent in writing within the first two weeks of the semester. □ Student Rights and Responsibilities: (Article 3.2.18) It is the responsibility of students to keep all assessed material returned to them and/or all digital work submitted to the teacher in the event of a grade review. (The deadline for a Grade Review is 4 weeks after the start of the next regular semester.) □ (Article 3.3.6) Student have the right to receive graded evaluations, for regular day division courses, within two weeks after the due date or exam/test date, except in extenuating circumstances. A maximum of three (3) weeks may apply in certain circumstances (ex. major essays) if approved by the department and stated on the course outline. For evaluations at the end of the semester/course, the results must be given to the student by the grade submission deadline (see current Academic Calendar). For intensive courses (i.e.: intersession, abridged courses) and AEC courses, timely feedback must be adjusted accordingly; □ Academic Procedure: Academic Integrity, Cheating and Plagiarism (Article 9.1 and 9.2) Cheating and plagiarism are unacceptable at John Abbott College. They represent infractions against academic integrity. Students are expected to conduct themselves accordingly and must be responsible for all of their actions. College definition of Cheating: Cheating means any dishonest or deceptive practice relative to examinations, tests, quizzes, lab assignments, research papers or other forms of evaluation tasks. Cheating includes, but is not restricted to, making use of or being in possession of unauthorized material or devices and/or obtaining or providing unauthorized assistance in writing examinations, papers or any other evaluation task and submitting the same work in more than one course without the teacher’s permission. It is incumbent upon the department through the teacher to ensure students are forewarned about unauthorized material, devices or practices that are not permitted. College definition of Plagiarism: Plagiarism is a form of cheating. It includes copying or paraphrasing (expressing the ideas of someone else in one’s own words), of another person's work or the use of another person’s work or ideas without acknowledgement of its source. Plagiarism can be from any source including books, magazines, electronic or photographic media or another student's paper or work.
