Across
- 8. A form of energy that travels through space as waves and includes visible light, X-rays, and radio waves.
- 10. When two waves combine to form a wave with a larger amplitude.
- 12. The maximum displacement of a wave from its rest position.
- 13. The substance through which a wave travels.
- 15. The spreading out of waves as they pass through a narrow opening or around obstacles.
Down
- 1. A type of wave where particles move parallel to the direction of wave propagation.
- 2. The bouncing back of a wave when it hits a surface it cannot pass through.
- 3. The distance between two consecutive crests or troughs of a wave.
- 4. The number of wave cycles that pass a point per second.
- 5. A type of wave where particles move perpendicular to the direction of wave propagation.
- 6. The distance a wave travels per unit of time.
- 7. The range of all types of electromagnetic radiation, from radio waves to gamma rays.
- 9. The change in frequency or pitch of a sound as the source moves relative to the observer.
- 11. The bending of a wave as it passes from one medium to another.
- 14. When two waves combine to form a wave with a smaller amplitude.
