...

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!: )
