It seems that you're describing an interactive activity where specific terms must be dragged into designated areas related to a wave diagram. However, you haven't provided the wave diagram or the potential terms to fill in the blanks.
Typically, a wave diagram may include terms such as:
- Crest
- Trough
- Wavelength
- Amplitude
To assist you better, please provide the details of the wave diagram or the list of terms to choose from, and I would be happy to help you identify which term should go in each response area.
