PHY132S Lecture 13 - EM Lecture 5 - Slide 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 ( ) “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- )

PHY132S Lecture 13 - EM Lecture 5 - Slide 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.

PHY132S Lecture 13 - EM Lecture 5 - Slide 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.

PHY132S Lecture 13 - EM Lecture 5 - Slide 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.

PHY132S Lecture 13 - EM Lecture 5 - Slide 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.

PHY132S Lecture 13 - EM Lecture 5 - Slide 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

PHY132S Lecture 13 - EM Lecture 5 - Slide 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)

PHY132S Lecture 13 - EM Lecture 5 - Slide 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 and 23-26, closed Reading Week Can just drop in (no need for appointment) Check the schedule at: /undergraduate/dic/dic-schedule.htm

PHY132S Lecture 13 - EM Lecture 5 - Slide 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.
