Date

Read over Course Expectations and Homework Guidelines.  Find a 3-ring binder and decide how you will use this to organize your notes, in-class handouts, labs, tests and homework.

E-mail me with a couple of potential times that we could meet in the next week or two.

Do #1-4, 9, 10 on Energy, Power and Efficiency -- A handout

NOTE:  I decided not to have you work on "Your Daily Activity"(the worksheet I handed out in class).  Please keep it in your notebook and we will try to return to it if we have time. 

Finish Significant Figures side of handout given in class

Significant Figures/Units Worksheet (already handed out in class - here is the link if you need it)

Do problems #1-4 on Unit Conversions Worksheet (from yesterday's homework)

Do problems #1, 4, and 6 on Energy, Power and Efficiency -- B worksheet

Bring laptops to class on Thursday

Do #2, 3, 5 on Energy, Power, and Efficiency -- B handout

Read Lab Write-up Guidelines (on General Physics page)

Create the data table for your lab report in Excel.

          *  A guide to Excel can be found on the main Science Webpage.  Pay attention to

              how to format your data table.

          *  A sample of what this data table might look like can be found here.

Do #29, 30 page 508

More with harmonics

Do #1, 9, 10, and 11 on Sound:  Interference handout

Start to review for test - Go over notes, old homework assignments and quizzes.  Create sheet with equations

LAB02 is due Thursday, October 19

TEST COVERING WAVES AND SOUND - Tuesday, October 10 (Thursday Sched.)

Sections from book: 

Page 442 of 12.2, 12.3, 12.4, All of Chapter 13 (except pages 502-503 on beats)

WORK ON LAB!!!  Do Steps 2 and 3 and start working on write-up.  Final lab is due Thursday, October 19.

Read 14.1 from book

Read 14.2 from book

Continue to work on lab

Work on Test Corrections.  Test corrections are due Friday, October 20.

For every problem that you missed (including problems that you missed 1/2 point on), include:

1)  The correct answer with an explanation of the correct answer for multiple choice problems/fill-in the blank problems

2)  A statement of why you got the problem wrong/what sort of mistake it was.

If you see "wbc" on your paper, it means "wrong but consistent".  I give you credit for problems that are wrong but consistent with an incorrect previous answer.  If you have one of these, please continue your corrections through so that all of your answers are actually and truly right!

PLEASE NOTE:  You will have a substantial homework assignment with problems to do tomorrow night and Thursday night.  Use tonight effectively!!

Read 14.3 (pages 530-536)

Keep in mind that we use do for p, di for q.

Pay attention to the difference between real images and virtual images.

Do each of the following problems by (A) equations and (B) ray tracing.  Here is the ray tracing sheet.

     Problem 1: do = 25 cm, ho = 2 cm, f = 10 cm, find di & hi.

     Problem 2: do = 8 cm, ho = 2 cm, f = 10 cm, find di & hi.  (Ray tracing this one is tricky!)

Read 14.3 (pages 537-542)

Do #2 & 3 on page 536

Do #2 & 3 on page 540 (keep in mind, the focal length of a convex mirror is negative!)

NOTE:  Magnification = -hi/ho

These problems are a little trickier than what we did in class, but can be solved if you work through the problem solving process.  Write down everything you are given and the equations that you could use to solve the problem

More with curved mirrors

Do #23, 24, 25, 26, 34 (this is more straight forward than the next two - do it if you feel like you need the practice), 47, 48 on pages 551-553

If it helps you to read from the book before hearing about new material, we will be covering Section 15.1 on Monday.

Quiz on Monday - Make sure you are familiar with ray diagrams

NOTE:  This is the assignment due Monday!!!!

Read 15.1 in book - look through sample problem 15A in book

Note:  the book uses subscripts "i" and "r" instead of "1" and "2" - it is still the same equation.

Do pages 1-3 on the handout and read through the explanation of Total Internal Reflection on the last page. 

Curved Mirror Worksheet - please finish

Take a look at the solutions after you are done.  Please drop by if you have any questions as we won't be going over it in class.
