 If you did, you can click on the file below to find resources that will help you prepare for the quiz.  Videos are posted on the "What is Light?" link at left.

#### Exam Prep

 I have posted the over view of content for the exam as well as 100 questions to spark your interest.  Check out the "Exam Prep" page from the link at left.

#### Wave-Particle Debate

 If you missed the lecture in class on Monday, May 21, check out the Wave-Particle Debate article that is posted on the "Light" page (click link from the list at left.)

#### Introduction to Waves

posted Apr 10, 2012, 2:56 PM by Lettie Weinmann

 Understanding waves is the key to understanding such complex phenomena as sound, light and earthquakes.  We begin our study of waves with the reading of Chapter 25 in the Conceptual Physics Book.  There is a reading guide (PS 30) posted under the assignments page at left as well as on the link below.

 This is a great site with videos, interactive simulations and lots of info about lightning storms.Lightning Web Page

#### Extra Practice with Coulomb's Law

posted Feb 22, 2012, 10:13 AM by Lettie Weinmann

 For those of you who wanted extra practice, try problem 11 and 16 on Page 552 of the Cutnell and Johnson book.  Both are rather long and involve many steps, but you should be able to see the big picture of how to solve each of them once you draw the diagram and figure out what they are asking for.  Detailed, worked out answers are attached to this post and posted under Assignments.  I called it ExtraCProbs or something like that.

#### Problem Set 22

posted Feb 19, 2012, 5:22 PM by Lettie Weinmann

 Problem Set 22 is due when we get back from our long break on Tuesday, Feb 21.  I have posted the two powerpoint presentations, Intro to Electro Statics and Coulomb's Law on the website under the Electrostatics page.  There are two worked out sample problems in the Coulomb's Law set of slides that may help you to work out the problem set.

#### It's Shocking!!!

 Our next unit is Electricity & Magnetism.  We will begin with static electricity - or electrostatics.  First we will build a conceptual understanding of electric charges and how they behave.    Please read Chapter 32 in the Conceptual Physics (Hewitt) textbook.  I did not assign any of the "Concept Check" questions at the end of the chapter, those questions are just checking to make sure that you know what you have read.  I suggest you use them to check your own understanding of the reading.The questions assigned for Problem set 21 are questions 23, 24,28,31,32,36,37,38  on pages 660-661.  They require an understanding of the material in the chapter so start with the reading....don't go straight to the questions!Problem Set 21 is due on Tuesday Feb 14.
