Types of Waves Crossword

2. Electromagnetic waves with wavelengths just longer than visible light, associated with heat.
4. Electromagnetic waves with the longest wavelengths and lowest frequencies, used for communication.
6. A wave that requires a medium to travel through, such as sound or water waves.
9. The unit of frequency, equal to one cycle per second.
11. Electromagnetic waves with the shortest wavelengths and highest frequencies, produced in nuclear reactions.
14. The region in a longitudinal wave where particles are close together.
16. The lowest point of a transverse wave.
20. The range of electromagnetic waves that can be detected by the human eye.
21. The difference between the resting point and the crest/trough.
22. The number of wave cycles that pass a point in one second, measured in hertz (Hz).
24. The substance or material through which a wave travels (e.g., air, water, solid).
25. The bouncing of a wave off a surface.

1. A wave that travels along the boundary between two different media, such as water waves.
3. The region in a longitudinal wave where particles are spread apart.
5. The distance between two consecutive crests or troughs in a wave.
7. A wave that does not require a medium and can travel through a vacuum, such as light.
8. High-energy electromagnetic waves used in medical imaging and security.
10. A wave in which particles move parallel to the direction of wave propagation.
12. Electromagnetic waves with wavelengths shorter than radio waves but longer than infrared.
13. The bending of a wave as it passes from one medium to another due to a change in speed.
15. A wave in which particles move perpendicular to the direction of wave propagation.
17. Electromagnetic waves with wavelengths shorter than visible light, capable of causing chemical reactions and skin damage.
18. Waves that travel through the Earth, caused by earthquakes or explosions.
19. The capacity of a wave to do work, often related to its amplitude and frequency.
23. The highest point of a transverse wave.
