Published by Addison Wesley 2007 (ISBN – 13: 978-0-321-50121-9)
Course components and weights:
11 Online Assignments 5%
5 Written Assignments 10%
Laboratory 20% (Minimum 50% required to pass the course)
Mid-term exam 20% (Wednesday, October 24, in class)
Final Exam 45% (14:00 Friday, December 7) Location TBA CONSOLIDATED EXAM
1. Online assignments are done electronically using the Mastering Physics system (Access free with purchase of new textbook or available separately). There will be approximately 1 assignment per week. If all 11 assignments are attempted, only the best 10 will be counted towards the final grade. Late assignments will be accepted until the end of term, but with an increasing penalty.
2. There will be 5 written assignments, each covering a major section of the course. Late assignments will be accepted with a 10 % penalty until the solutions are posted. Once the solutions are posted, late assignments are worth zero.
Final Grades will be decided based on University of Alberta Policy. Final grade allotment will be based on a combination of the expected distribution and observed patterns in the actual percentage distributions. This is a multi-section course and grades will be consistent with historical trends both within each section and overall for the entire course.
"The University of Alberta is committed to the highest standards of academic integrity and honesty. Students are expected to be familiar with these standards regarding academic honesty and to uphold the policies of the University in this respect. Students are particularly urged to familiarize themselves with the provisions of the Code of Student Behaviour (online at www.ualberta.ca/secretariat/appeals.htm) and avoid any behaviour which could potentially result in suspicions of cheating, plagiarism, misrepresentation of facts and/or participation in an offence. Academic dishonesty is a serious offence and can result in suspension or expulsion from the University."

Course outline:
This course is designed to be an introduction to University Level Physics, specifically for students interested in Engineering. It is assumed that these students have mastered or at least been exposed to certain basics in physics (Classical Physics - forces, Newton’s Laws, momentum, geometrical optics, waves, etc), plus some more advanced topics including some quantum physics (The Hydrogen atom, energy levels, the electromagnetic spectrum, etc). The course covers periodic motion, oscillations, mechanical waves, sound waves and light (properties, geometrical optics and interference).

A brief introduction to problem solving in physics
Physical quantities (Standards and Units)
Error, Uncertainty and some math
Part 2: Oscillations (Chapter 13)
Relation to circular motion
Definition of periodic motion and its parameters
Displacement, Velocity, Acceleration and Energy for harmonic oscillators

Damped oscillations, forced oscillations and resonance
Part 3: Mechanical waves (Chapter 15)
Transverse and longitudinal waves
Sinusoidal mechanical waves, wavelength and frequency
Wave speed and particle speed
Superposition of waves

Total internal reflection and fiber-optic applications
Part 6: Geometric optics (Chapter 34)
Conditions for forming an image
Real and virtual images
Geometrical Optics of Mirrors
Refraction by spherical surfaces

Light waves in different media, path difference
Origin of interference from Huygen’s Principle
Young’s double-slit experiment
Intensity of the Young’s fringes
Interference from uniform thin films

Part 8: Diffraction (Chapter 36)
Single slit diffraction experiment
Locating the dark fringes on the diffraction pattern
Angular dependence of the intensity in the diffraction pattern
Diffraction by a circular aperture
Rayleigh’s criterion and resolution
Diffraction by a double slit
Missing maxima in the interference pattern
Multi-slit diffraction, diffraction grating
This list is general. Not all topics listed above will be covered with the same degree of detail. Additional/alternate topics may be covered depending on time constraints and student interest.
IMPORTANT NOTES:
1. YOU MUST PASS THE LABORATORY SECTION (minimum 50 % average) TO PASS THE COURSE.
2. MID-TERM EXAMINATIONS MISSED FOR ANY REASON WILL NOT BE RESCHEDULED. Students not writing the midterm exam, with a valid excuse (as defined by University policy) will have the midterm weight added to the final exam. This is not automatic, and if you miss the mid-term, you should follow all University guidelines and contact your instructor as soon as possible.
3. FORMULA SHEET: A single standard 8.5” x 11” sheet of paper with student written notes may be used in both the Mid-Term and Final examinations.
4. CALCULATOR POLICY: Any type of calculator without communications features may be used during examinations. Palm pilots, Blackberries, laptop computers, etc. are prohibited. Cellular phones must be shut off during exams.
