Reflection
Question
-
After developing explanations using motion, graphs, models, etc., what do you understand better? What can you explain now that you could not before this assignment?
-
Did some representations support your understanding better than others? Why?
-
What do you still wonder? What questions did this bring up or what is left unanswered even after your investigation?
-
What supported your group in working together? You may co-write the answer to this question.

First and foremost, by conducting experiment and analyzing academic pictorial representations such as FBD and chart, now I have a better understanding of the nature of sound in general and some of its characteristics in particular. Before doing this project, even though I had some basic knowledge of sound, that is still not deep understanding. Typically, when talking about sound, I have to use the concept wave to explain, and even sometimes I cannot explain it completely. However, in this project, I tried to explain concept sound as simply as possible while still avoiding the concept of waves, so I was forced to dig deeper to understand the problem, thereby thoroughly explaining it.

Conducting experiment by myself and having graph from Logger Pro help me the most in understanding these concept. Simply because they are visual representations (real-time data) of conceptual idea. Because I have to think of ways that make those with little knowledge in physics understand my presentation, I have to try and create an experiment as simple as possible. This is also the process that let me break down every little parts of the problem, so even myself can understand it clear.

I would say the question needed for this project have all been answered. Although the fact that I didn't try to explain the following sound-related question since it is outside of my plan, working through this project simply make me wonder about them. How loud can a speaker play theoretically? What are the other aspect of sound (dispersion, reflection, dampening effect based on materials? How can speaker amplifier create alternative current (class D amplifier in my case)? Et cetera. Literally, I've just cover a really small part of acoustics science.
