Discussion Overview
The discussion revolves around the comparison of two kinds of waves, specifically how they can be perceived from different perspectives. Participants explore the nature of the waves and seek clarification on their similarities and differences.
Discussion Character
- Exploratory
- Conceptual clarification
- Debate/contested
Main Points Raised
- One participant notes the equation ##\ddot y +y =0## but seeks clarification on its relevance to the comparison.
- Another participant asserts that the two kinds of waves are not the same and requests additional context for the question.
- A different participant highlights the need for more information, pointing out the disparity in the types of waves being compared.
- One participant describes a scenario involving a large surface of water, explaining how waves can be viewed from different angles, which leads to a better understanding of the comparison.
- Several participants express appreciation for the explanation provided, indicating that it clarified their understanding of the topic.
Areas of Agreement / Disagreement
Participants do not reach a consensus on whether the waves are the same, as some assert they are different while others suggest they represent similar phenomena from different perspectives.
Contextual Notes
The discussion lacks specific definitions of the types of waves being compared, which may affect the clarity of the comparison. Additionally, the mathematical context of the equation mentioned is not fully explored.

I only see ##\ddot y +y =0.## What do you mean?

They aren't the same.
Perhaps you could add some context to the question.

What are we comparing? There is one kind of this on the left hand side and two kinds of thises on the right hand side. This goes to show that we need more information on this.

Imagine a large surface of water. Now imagine that this water is waving in one direction. At every point on the surface of the water, the waves are moving in the same direction. If you were to look at the surface of this water from the side (perpendicularly to the direction of wave motion), you would find that the surface looks like your image on the left.
Now move your perspective so that you are looking at the same surface of water from above. It's a nice sunny day, and the sunlight reflects off of the top of the waves, while casting a shadow in the troughs. This is essentially what you are seeing on the left side of the right image. The purple spots are the crests of waves, while the dark spots are troughs.
In short, they both represent similar waves, but from different perspectives--one from the side, and one from above. Hope this helps!
