So, what we did on Friday is we went over the A.Two-Dimensional Waves and the Ripple Tank, B.Wavefronts and Wave Rays, C.Reflection from a Straight Barrier: Wavefronts, D.Reflection from a Straight Barrier: Wave Rays and a little bit of section E.Reflection of Circular Waves from a Straight Barrier from the blue booklet: Two Dimensional Waves.
Wavefront - is a continuous crest and trough.
Wave Ray - is an arrow at right angles to the wavefront.
We also did the Exercises sheet. Here are some examples that we went over through.
Wavefronts are always perpendicular to the waveray.
This an example of a Reflection from a Straight Barrier.
<--Incident waves
Reflected waves-->
The incident waves approaches a straight barrier and then reflected back along its original path.
Angle of Incidence = Angle of Reflection Angle of Incidence for the wavefront is the angle between the incident wavefront and the barrier.
Angle of Reflection for the wavefront is the angle between the reflected wavefront and the barrier.
Angle of Incidence for the wave ray is the angle between the normal and the incident wave ray.
Angle of Reflection for the wave ray is the angle between the normal and the reflected wave ray.
Normal is the straight line that is perpendicular to the barrier.
Before the end of the class, she gave us the sheet Waves in Two Dimension - Assignment 1 that needs to be hand in on Tuesday, September 23.
I apologize for the late post guys and hopefully i gave you enough information to understand the topic. The next scribe will be mark aquino. So yea, see you all in class and take care.=)
