18. amplitude is the _______________ of the wave.
19. the longer the whistle is the _____________ the waves and the _____________ the note.
20. waves can carry _______________ from one place to another.
21. do all waves move up and down?
22. sonar uses sound waves to find things _______________.
23. what are 2 things that use sonar?

Explanation:

1. Water moves with a force.
2. The description about water movement is incomplete in the given text, but generally water can flow and ripple.
3. The distance from crest - to - crest is the wavelength.
4. Waves that come often have a high frequency.
5. High - frequency waves have more wave cycles in a given time compared to low - frequency waves.
6. Low - frequency waves have a long wavelength.
7. High - frequency waves have a short wavelength.
8. All waves have a repeating shape.
9. Energy moves in waves.
10. We see different wavelengths as different colors.
11. Three examples of electromagnetic waves are radio waves, visible light, and X - rays.
12. The only difference between different electromagnetic waves is the wavelength (or frequency as they are inversely related).
13. Radio signals are electromagnetic waves.
14. X - rays have a lot of energy and can travel through skin and bones.
15. Earthquakes can travel in seismic waves.
16. The surface of the Earth is floating on molten rock (magma).
17. Earthquake waves are called seismic waves.
18. Amplitude is the height (or maximum displacement) of the wave.
19. The longer the whistle is, the longer the waves and the lower the note.
20. Waves can carry energy from one place to another.
21. No, not all waves move up and down. For example, longitudinal waves move back and forth.
22. Sonar uses sound waves to find things underwater.
23. Two things that use sonar are submarines and fishing boats.
