Hi hi! This is Ryan and I will be the scribe for today =). Today in class we started off with our Waves in 1Dimensions Test. Then after the test Ms.Kozoriz handed us our old homework from previous classes.

They were:

• The Job Description (Why is Physics used in this Career)


• Concept-Development Practice Page 25-3 (Wave Superposition)

The next thing that Ms.Kozoriz handed to us was a new booklet entitled "Waves in Two Dimensions," and also an Excercises sheet. We must read pages 3-4 in the booklet. And after she handed that to us she explained that "Wave fronts are always perpendicular to wave rays." And here is a picture I made on paint that she drew on the board. =).

• The Red Square shows that it is perpendicular
• The Grey Dashed Arrow is the Wave Ray
• The Black Lines are the Wave Fronts
• The space inside the Wave Fronts is the Wavelength or Lambda

And that was pretty much it that we did in class. Ahahaha I thought scribing would be harder but it isn't =/ ahaha. Well anyways that is it. OH and I forgot that you need to be bring:

• Protractors
• Rulers

Because we would be making lots of pictures and such. So I will end my scribe here, and next scribe knows who they are so yeah. See you all in class. XD
