STEP ONE: Change the drop down window from 1 src, 1 frq to No sources Click the mouse at random in the window. You can increase the brightness if this helps. 1. Describe the shape of the pulse. Does the speed of the pulse seem to be the same in all directions? It is square ripples centered around the mouse and then they turn to circles. The ripples are even all the way around.
STEP TWO: Change the drop down window from No sources to 1 plane src, 1 freq. You can change the simulation speed and source frequency if you want. 2. What is the shape of the pulse? How is this different than your point source? It is circles immediately after being created from the source instead of starting out as squares and then becoming circles. STEP THREE: Change the setup to obstacle.
3. What does the pulse do when it reaches the obstacle? What does the pulse do when after it hits the barrier? It is directeed around the obstacle and after the obstacle it begins to go back to the center or behind the obstacle.
STEP FOUR: Keep the obstacle, but have No Sources.
4. Click at random. How do the pulses reflect off the obstacle? It is directeed around the obstacle and after the obstacle it begins to go back to the center or behind the obstacle.
STEP FIVE: PLAY AROUND but try to answer these questions.
5. What happens to waves when they encounter obstacles of different shapes? Why do you think that happens? Well, there is more ripple interference and the shape remains circles but not perfect circle ripples all around. This happens because they are reflected off of different shaped objects and not just flat objects sending the ripples in multiple directions. 6. How does the wave pattern for a single slit vs. a double slit compare? Why do you think that happens? They are very similar but the the single slit has less waves being spread out after the slit and the double slit has more even and wider ripples after the slit. This is happening because when there is only one slit it just being displaced right in the middle and basically keeps one main ripple afterwards. When there is two, there is more displacement and the ripples become more spread out. 7. How does a plane source vs. plane source interact with an obstacle of different shapes? Why do you think that happens?
The Essay on Our Identity Is Shaped by Our Relationships
Good morning/afternoon everyone, my name is Jessica Holmes and I’m coming from the VCAA education department. I’m here today to talk to you about how, “our identity is shaped by our relationships”. When I say relationships, I don’t just mean boyfriend/girlfriend relationship, I’m also talking about family, friends and other relationships. I’m talking about identity since it’s your context writing ...
8. Examine a moving source. Describe the wave patterns behind the source. What happens when you change the frequency? The speed? When a source is moving it reminds me of a boat moving through water, the ripple behind it starts out small and then continues to grow. When the frequency is increased it just creates more waves and same goes for when its decreased, less waves. Although when the source speed is changed the waves act different. When it is extremely slow the waves are created all around the source and not just behind it, but when it is fast that’s when the waves are just created behind the source. 9. Generate some wave (either plane or single source).
What happens when you click on the wave pond? Why do you think that happens? It generates alittle displacement and creates the square shaped ripples but then the ripples continue on and go back to even ripples of circles.
10. Compare single source vs. multiple source. What happens with the wave patterns? Why do you think that is? A single source creates the ripple effect with just circles but when there is multiple they collide and form a checkboard style ripple. I think this happens because the waves still continue on their path but create the illusion that they are going in mulitple directions. I did four sources and this created the checkerboard style ripples. 11. Describe some other condition that you observe with the ripple tank. What happened? How do you observe this? Why do you think this happens? I observed the “half plane” setup and the ripple is straight lines rather than circles. The ripples attempt to go back to circles behind the half plane but where the opening is, the ripples are straight lines. I think this happens because the inteference of the half plane is making the ripples flow a certain direction and they aren’t able to fully go back to circle ripples.
The Essay on Closed-Source Systems
There are several differences and similarities when discussing open and closed source software or systems. Some operating systems that are currently in operating are closed source and some of them are open source. Both closed and open source software / systems have their place in the technical world. It is difficult to say which of these types is better, because it will usually be based on ...
