Across
- 3. – The crowded part of a longitudinal wave.
- 5. – When a wave bounces off a surface.
- 8. – One complete back-and-forth motion of a wave.
- 10. – A repeating movement that transfers energy through space or matter.
- 11. – The time it takes for one full wave to pass a point.
- 12. – The highest point of a wave.
- 13. Wave – A wave where motion is parallel to the direction of travel.
- 15. – How many waves pass a point in one second.
- 16. – A rapid back-and-forth movement that creates a wave.
- 19. – The power carried by a wave.
- 20. – The material through which a wave travels (like water or air).
Down
- 1. Wave – A wave where motion is perpendicular to the direction of travel.
- 2. Wave – A wave that can travel through empty space (e.g., light).
- 4. – When a wave changes direction as it enters a new medium.
- 6. – The height of a wave from its middle point to its peak.
- 7. – The distance between two matching points on a wave (like crest to crest).
- 9. Wave – A wave that needs a medium to travel (e.g., water waves).
- 14. – The lowest point of a wave.
- 17. – When two or more waves overlap and combine.
- 18. – The spread-out part of a longitudinal wave.
