PHY132 – Review for Mid-Term Test

1. PHY132 – Review for Mid-Term Test “Examinations are formidable even to the best prepared, for the greatest fool may ask more than the wisest man can answer.” Charles Caleb Colton, English writer (1780-1832) “I was thrown out of college for cheating on the metaphysics exam; I looked into the soul of the boy sitting next to me.” Woody Allen, American actor & director (1935- )

2. PHY132 Mid-Term Test – General Comments • 6:10 - 7:30 PM, Tuesday, February 24 • It is mandatory that you go to the room assigned to your tutorial group. • Test information and room assignments are on the PHY132 home page via the Portal • You should have no communication device (phone, pager, etc.) within your reach or field of vision during the test.

3. PHY132 Mid-Term Test –Format • Format - similar to PHY131 Mid-Term Test • 9 equally weighted multiple-choice questions • Each question has 4 or 5 possible answers. • Each correct answer will be awarded 7 marks. • Blank, incorrect, and multiple answers get 0. • A long-answer section for 37 marks • Two questions: one short, one multi-part • Will be graded in detail with part marks awarded as appropriate only if you show your work. • The test will be marked out of 100 points.

4. PHY132 Mid-Term Test – Don’t Forget ... • Your student card. • A non-programmable calculator without text storage and communication capability. • A single original, handwritten 22 × 28 cm sheet of paper on which you have written anything you wish on both sides. • Numerical constants will be provided. • One or more dark-black, soft-lead 2B or 2HB pencils and an eraser.

5. PHY132 Mid-Term Test – Some Advice • A good aid-sheet is well organized, easy to read, and contains all the major equations from the assigned sections from the reading. • Copies of detailed specific problem solutions are unlikely to help. • Be ready to think; get a good night’s sleep tomorrow night.

6. PHY132 Mid-Term Test – Material Covered 1 • All material from Lectures 1 through 13 • Waves & Oscillations and Electromagnetism • This includes • All assigned sections from the textbook, whether they were discussed in the lectures or not • Lecture notes - sidescreen and tablet • All figures and diagrams discussed • MasteringPhysics questions • Practicals

7. PHY132 Mid-Term Test – Material Covered 2 • The test includes conceptual and calculation questions • The test does NOT include • Supplementary material not discussed in class • Integration (BUT you should know the integral and derivative relationships that we’ve covered)

8. Physics Drop-In Centre • Location: MP200, right above main lobby • Help desk is in small room at North end of Centre • Extended Hours: 10AM - 5PM, Feb. 9-12 and23-26, closed Reading Week • Can just drop in (no need for appointment) • Check the schedule at: http://www.physics.utoronto.ca/undergraduate/dic/dic-schedule.htm

9. The Waves Section: 8 Classes in 10 Slides • The text and our classes often introduced material in a spiral fashion: the various concepts were introduced in pieces. • Here I try to make the review of that material more linear. • Therefore the review will not always be in the order in which the material was discussed.

20. PHY132 Mid-Term Test – Electromagnetism Review • Chapter 26 - all sections • Chapter 27 - §27.1, 27.2, 27.5 • in §27.3, we used Equation 27.14 (page 825) • in §27.4, we used Equation 27.26 (page 832) • Chapter 29 - §29.1, 29.2, 29.3

22. Electric Fields The electric field describes the electric force on a test charge at any point in space.

23. Electric Field Lines (for a Dipole) Tangent to field line is in the direction of the electric field at that point. Electric dipole moment:
