To label the parts of a wave, here's the correct placement for each term:
- Crest - The highest point of the wave.
- Trough - The lowest point of the wave.
- Amplitude - The distance from the rest position to the crest or trough.
- Wavelength - The distance from one crest to the next crest (or from one trough to the next trough).
If you provide the visual representation of the wave or specific points, I can assist further in detailing where to drag and drop these terms.
