Waves in 2D

Yeao!!! Lawrence here signing in. Sorry about it being so late but I had a football game and some other things going on within the family plus I had homework so yeah. Thanks for being so considerate Justus ¬__¬''

ANYWAYS, We started off class with a lovely test. Isn't that just dandy.

Then, we received a second booklet entitled: " Waves in Two Dimensions'' and we practically looked at circular waves, which can be generated on the surface of a liquid by a point source such as a drop of water, or a drop of any kind of object for example, your finger. Also, we learned that if a crest or trough is continuous, it's referred to as a wavefront. To show how the wave is traveling, we just simply create an arrow at right angles to the wavefront, in which this line is called the wave ray.

*Pictures can be located in your booklets on the back of the first page.*

Next, we looked at reflections. To put it simply, the wave ray is bounced back at exactly the same angle it hit the barrier, so if it hits the barrier straight on, it'll reflect straight back, thus, if it hits a barrier at a forty-five degree angle, it'll bounce off the barrier at a forty-five degree angle, in which we can presume the angle of incidence is equal to the angle of reflection.

*Angle of Incidence is the angle between the incident wavefront and the barrier while the angle of reflection is the angle between the reflected wavefront and the barrier.*

It'll look a little something like this :

I think that about does it, and I know its late but just to let you know, we have that paper due next Tuesday as well as homework.

Also, the Next scribe shall be...
