February 28, 08 .

In class today, we went over the questions from the worksheet called Interference Exercises. We also went over the review for Waves in two dimensions. These two were basically a review for tomorrow's test in Waves in two dimensions. Not very much activities but it was a very useful review if you listened and understood each questions done on the overhead and smart board (:

Reminder that there will be a test tomorrow on waves in two dimensions so make the right decision, open your binder and read over those notes, study study !

(: goodluck!

Waves in 2D review

today's class

wow...life goes on...."remember that tomorrow always come after the dark" and believe that tomorrow you will be better than today so we all better work hard to success.
Anyways let's get to the point...today's class was kind of busy
we learned about the Nodal lines, and the teacher showed us how it does on the smart board,
she did handout 2 sheets to work on. we started working on some question in the green book, i don't know if some students finished.

keep in mind that friday we still have a test. Better study, this topic seems difficult.

Refraction Work Sheet

Good evening people! To start a beautiful Tuesday morning, we answered questions on a refraction worksheet entitled "Refraction". Crazy eh? We answered the questions on the almighty Smart Board, so if you need the answers, look below this post. It was basically a work sheet based on using the formulas: n=c / v and n_i sinθ_{i =} n_r sinθ_r. After we finished that, she gave us a sheet that talks about diffraction, which is entitled "Diffraction". Who would have thought... Anyways... The sheet just sums up the three pages we should read in the booklet "Waves In Two Dimension". We were then assigned to work on questions 5 to 11 in that very same booklet. She gave us the rest of the period to work on those questions and a little booklet called "Waves in Two Dimension - Review" that she gave us as well. It's obviously a review for Friday's test. Speaking of which...

REMINDER:
Waves in Two Dimensions Test
Friday, February 29, 2008 (it's a leap year! =D)
9:00 am, in Room 29 (obviously)

Anywhoots, that's it, that's all, that's what went down. Happy studying! =)

Today's class !!!! =)

In today's class, we corrected the previous sheets that we've been working on. We went over the problems in the booklet, questions #1- #4. We also finished correcting the Snell's law questions. The answers can be found on the blog. After correcting the worksheets, we received three new worksheets to do this weekend (Reflection & Refraction, Exercises-Refraction, and Light-Refraction) .

Well, that's all we did today! I think =\
Reminder: TEST NEXT WEEK!! don't forget to study!!!

Have a great long weekend everybody!!

so who wants to scribe next?!?

Snell's Law Problems

Febuary 20, 2008

Today in class we did an experiment which shows how light changes in different mediums, we used a semi-circle shaped clear-plastic cup and poured a quarter of water into it. Then we placed it on graph paper on a center like and outlined it. Then we drew lines on the graph that point toward a line on the cup, one on flat side, one on curved side. Then we figured out the angle of incidence and angle of reflection and then divided the sin of angle of incidence by the sin of angle of refraction to get n.

Physics 30S, Feb. 19, 2008

Previously in class, we looked over the law of reflection in circular and parabolic barriers. The 5 question assignment of reflection laws was due and we were assigned to read the waves in two dimensions booklet.

Scribe

Hello,

This is my scribe for February 14. I originally intended my scribe to be uploaded in slideshare using the technology of smartboard. Slideshare led to technical difficulties thus I created image files of my slides instead. ENJOY...

bonjour tout le monde ! / hello everyone (:

I will be recounting all of the things that we've done in class for the past 2 days ..

Monday - we were given a small, pink sheet of paper that has all the informations we need for our Waves Research Project. But if you have not received this sheet of paper, I will type all the informations later on in this blog.
- we then went to the Maclab to start our research for this project (:

Tuesday - today, we went over all of the 4 worksheets that Rojuane have mentioned earlier.
These worksheets were :
- Periods & Frequency Problems
- 14.5 Wave Properties
- Concept Development Practice Page/ vibrations and waves
- Vocabulary Review
Most of these worksheets are a preparation for tomorrow's test .
TEST! YES! there will be a test tomorrow!! and sorry i know this is quite a late reminder. But do not worry, we can all do a great job on this test if we read pages 3-11 on the green booklet and understand every single bit of it ! (: And remember, those 4 worksheets can be your big helper .
Goodluck ya'll (:

Grade 11 Physics: Waves Research Project
Investigate the historical development of 1 of the following communication technologies that uses waves: telephone, radio, television, cell phone, communications satellite, motion detectors, remote controls

1. Your research paper should be word processed and about ONE page length.
2. References must be noted down. When using the internet, write down the website where you obtained the information. Give credit where credit is due.
3. Your paper must be written in your own words. Don't copy information directly from a book or the internet.
4. Due Date for this paper is Friday, Feb. 15
5. Assignment is worth 15 marks

the next scribe is Dana (:

Hi everyone !

Well, on Friday in class we corrected the worksheet that we got on Thursday called:
CHARACTERISTICS OF WAVES: PHYSICS 30S. Then we got 4 of worksheets
and we got to take a textbook home if we wanted to. So if you want one just ask and
don't forget to sign it out. The worksheets are:

CHAPTER 14: Vocabulary Review
CHAPTER 14: Study Guide
Physics 11: Period & Frequency Problems
Chapter 25: Vibrations and Waves

We were not given a due date so don't freak out if you don't finish.
See you all in class tomorrow and make sure you get those worksheets from Ms.K !

OH YEAH ..
The Slinky Lab was due on Friday :)

The next scribe is annne !
