Friday's class

Friday, november 21/2008
In class we had a subtitute. I dont quite remember what her name was, but anyways..In class we were given a few things to do.
1.) Read 6.1 & 6.2 (p.110- 119)
Graphical and Analytical Vector addition
2.)End of chap Q's: p.129 #1-7 (6.1 Q's)
-> (fig 6-25 p.128)
-> 4 for #2, 5 & 6
im pretty sure thats all we did, no homework because we couldn't take the book home, so yeah if i missed anything else , tell me and ill fix it.

By the way this is erica maquimot scribing for last friday instead of aldrin.
And the next scribe is : anthony lee .

November 14 && 17, 2008

--------Friday, november 14,2008 -------
In physics class, we corrected the test on the supporting arguments of both particle and wave theories of light. It was out of 30 and it was calles Nature of Light II.... here are the corrections :

1. a.) Rectilinear Propagation: Light travels in straight lines, and its very fast.
example: a ball thrown quickly travels straight.
b.) Reflection: angle of reflection equals angle of refraction.
c.) Refraction: Light moves slower on a less dense medium.

2.a.) Rectilinear Propagation:


b.)Reflection: angle of reflection equals angle of refraction

c.) Refraction: light travels in a more dense medium


3.) State 2 properties of light that Newton couldn't explain very well with his particle model.

-Difraction -Partial reflection/ refraction

4.) (about your choosen scientists)

5.)


6.) (c.) wavelength of light
7.) (a.) electromagnetic wave
8.)

9.) Einstein stated that light was not transmitted as a continuous wave. He proposed light was transmitted as a photon and his famous experiment was the photoelectric effect.
10.) wave, then particle.

Alsoo on friday we took down notes :) ....
Kinematics
Scalars - number, unit
-distance
-temperature
- time
- speed
-mass
-energy
Vectors
- number, unit + direction
- position
- displacement
-velocity
- force
- weight
- acceleration

Time
Instantaneous time: clock reading
Time interval: difference between 2 clock readings

After taking down notes we were given a short worksheet and then we corrected it.
....that was all for friday.
-----Monday, November 17, 20008-----
Todays class we just did lab. Actually half of the class did lab and others, worked on worksheets that we were given. The lab was just to try and experience how the position time graph goes.
Ohh yeah..... in the end of the class were told to hand in the worksheet that were given for homework last friday. thats pretty much all we did :) kaaay see you all tomorrow!!

THE NEXT SCRIBE : yvanne dandan.

...

Guess who's the scribe for last friday..yes , you guessed right its me erica, yeayy!

First of all, remember the 4 questions we had for homework last Thursday on page 19 on the blue book? (Title: Waves in Two Dimensions Problems )
We corrected them and here are the answers:

... And also last Friday we watched a video called “Reflection and Refraction”. While watching the video, we were given a sheet, titled “ Physics 11 Waves in Two Dimensions Unit: Reflection and Refraction. Were asked to answer the following questions. The guuureeaat thing about last friday was that we didnt have homework: )

oOYeah, we also have a new student in our class, his name is Aldrin. WELCOME Aldrin ,have a great school year.

......Another thing is that we finished the pharagraph on the study guide booklet:

Diffraction and Interference of Waves

When waves reach a small opening in a barrier, they form circular waves that spread out from the opening. This spreading of waves is called Diffraction. The smaller the waveleght in comparison to the size of the barrie, the less the diffraction. When ther are two opening in a barrier, two sets of circular waves are produced. When the new waves interfere with each other, constructive interference produce large waves, and desctructive interference produces a line of nodes.

Thats pretty much all we did last friday, soo the next scribe will be...innnie minnie miney moe, i choose JUNNEL!, your very welcome, muauuaahhahaa!: )
