Step-by-step solution for: Labeling Parts of a Wave
You’ve uploaded an educational worksheet titled “Labeling Parts of a Wave”, which is designed to teach the key components of a transverse wave using a labeled diagram and a word bank with definitions.
---
✔ The task is to match each term (Crest, Trough, Wavelength, Amplitude, Equilibrium) with its correct definition and understand how they relate to the wave diagram.
Here’s the solution with explanations:
---
> Definition: The highest point of the wave
> ✔ Explanation: In the diagram, the crest is the topmost peak of each wave cycle. It represents the maximum positive displacement from the equilibrium position.
---
> Definition: The lowest point of the wave
> ✔ Explanation: Opposite of the crest, the trough is the bottom-most dip in the wave. It represents the maximum negative displacement from equilibrium.
---
> Definition: The distance between any two points of the wave; measured from crest to crest or trough to trough
> ✔ Explanation: Wavelength (often denoted by λ) is the length of one complete wave cycle — for example, from one crest to the next crest, or one trough to the next trough. In the diagram, it’s shown as the horizontal distance between two crests (or troughs).
---
> Definition: The distance between the equilibrium and the crest or trough
> ✔ Explanation: Amplitude measures the height of the wave from the center line (equilibrium) to either the crest or trough. It indicates the wave’s energy — larger amplitude = more energy. In the diagram, it’s shown as a vertical arrow from the equilibrium line to a crest.
---
> Definition: The “middle point” around which the wave moves
> ✔ Explanation: Also called the rest position or baseline, this is the horizontal line where the medium would be if no wave were present. The wave oscillates above and below this line.
---
📌 Bonus Tip: How to Remember These Terms
- Think of ocean waves: Crest = top of the wave you surf on; Trough = the valley between waves.
- Wavelength = how long one full wave is (from peak to peak).
- Amplitude = how tall the wave is (from middle to top).
- Equilibrium = calm water level before the wave arrives.

✔ Final Answer Summary (Matching):
| Term | Definition |
|--------------|------------------------------------------------------------------------------|
| Crest | The highest point of the wave |
| Trough | The lowest point of the wave |
| Wavelength | The distance between any two points of the wave; measured from crest to crest or trough to trough |
| Amplitude | The distance between the equilibrium and the crest or trough |
| Equilibrium | The “middle point” around which the wave moves |
This worksheet successfully teaches foundational wave vocabulary — essential for understanding sound, light, and other wave phenomena in physics!

✔ The task is to match each term (Crest, Trough, Wavelength, Amplitude, Equilibrium) with its correct definition and understand how they relate to the wave diagram.
Here’s the solution with explanations:
---
🔹 1. Crest
> Definition: The highest point of the wave
> ✔ Explanation: In the diagram, the crest is the topmost peak of each wave cycle. It represents the maximum positive displacement from the equilibrium position.

🔹 2. Trough
> Definition: The lowest point of the wave
> ✔ Explanation: Opposite of the crest, the trough is the bottom-most dip in the wave. It represents the maximum negative displacement from equilibrium.

🔹 3. Wavelength
> Definition: The distance between any two points of the wave; measured from crest to crest or trough to trough
> ✔ Explanation: Wavelength (often denoted by λ) is the length of one complete wave cycle — for example, from one crest to the next crest, or one trough to the next trough. In the diagram, it’s shown as the horizontal distance between two crests (or troughs).

🔹 4. Amplitude
> Definition: The distance between the equilibrium and the crest or trough
> ✔ Explanation: Amplitude measures the height of the wave from the center line (equilibrium) to either the crest or trough. It indicates the wave’s energy — larger amplitude = more energy. In the diagram, it’s shown as a vertical arrow from the equilibrium line to a crest.
---
🔹 5. Equilibrium
> Definition: The “middle point” around which the wave moves
> ✔ Explanation: Also called the rest position or baseline, this is the horizontal line where the medium would be if no wave were present. The wave oscillates above and below this line.
