Quiz Answer Key

1. The dx slider controls the distance between each block in the simulation. Adjusting it changes the spatial resolution of the wave visualization; a smaller dx shows more points and potentially a smoother wave, while a larger dx shows fewer points and a coarser wave.
2. The delay slider introduces a delay in the vertical movements of different parts of the wave. This can be used to visualize how different points along the wave oscillate out of phase or with a time lag.
3. Users can initiate the simulation by dragging the provided arrow vertically. This action directly inputs energy into the system, causing the wave to propagate based on the dragging motion.
4. The "Step" button allows the user to advance the simulation by a single time increment, enabling detailed observation of the wave's evolution. The "Reset" button returns the simulation to its initial state, allowing for repeated experimentation.
5. The "Embed" option suggests that this interactive simulation is intended to be used within other webpages or online learning platforms through the use of an iframe.

• JavaScript: A high-level, often just-in-time compiled programming language that conforms to the ECMAScript specification. It is commonly used in web development to make web pages interactive.
• Simulation: A computer model designed to represent the behavior or characteristics of one physical or abstract system. Simulations allow users to manipulate variables and observe the resulting changes.
• Open Educational Resources (OER): Teaching, learning, and research materials in any medium – digital or otherwise – that reside in the public domain or have been released under an open license that permits no-cost access, use, adaptation, and redistribution by others with no or limited restrictions.
• Slider (in UI): A graphical control element that allows the user to select a value by moving an indicator along a fixed track.
• Embed (in web context): To integrate content from one website or resource into another, often using an iframe or similar HTML elements.
• Phase Difference: The difference in the phase of two or more waves with the same frequency that are propagating together. It describes the extent to which the waves are out of step with each other.
• Wavelength: The spatial period of a periodic wave—the distance over which the wave's shape repeats. It is usually determined by considering the distance between consecutive corresponding points of the same phase on the wave, such as two adjacent crests or troughs.
• Frequency: The number of occurrences of a repeating event per unit of time. In wave phenomena, it refers to the number of complete wave cycles that pass a fixed point in one second, measured in Hertz (Hz).
