Across
- 3. Interaction of a wave when it bounces off a surface it cannot pass through
- 6. Material through which a wave carries energy
- 7. Distance between a point on one wave and the same point on the next cycle of the wave
- 10. Apparent change in frequency due to moving objects
- 13. A wave where the vibration is perpendicular (right angle, 90°) to the direction of motion and the particles move up and down
- 14. Time it takes for one complete cycle of a wave to pass a given point and is measured in seconds
- 15. Two or more waves facing opposite directions combine and the smaller wave destroys part of the larger one
- 18. A wave where the vibration propagates (moves) in the same direction as the movement of energy. They are compression waves
- 19. The lowest part of a transverse wave
- 21. Waves bend when entering a new medium at an angle
Down
- 1. = wavelength ✕ frequency
- 2. Part of a longitudinal wave area where the particles in the medium are spread out
- 4. A wave that is a combination of compression and transverse and the surface particles move in circles
- 5. Waves bend as they move around an obstacle or through a narrow opening
- 6. A wave that travels through a medium and is created when a different form of energy causes a medium to vibrate
- 8. A wave that is made of a pair of perpendicular transverse waves and is produced when a charged particle accelerates or vibrates
- 9. Two or more waves facing the same direction combine and construct a larger wave
- 11. The number of complete cycles of the wave in a given time and is measured in Hz
- 12. The height of the crest or depth of the trough relative to the resting (original) position on a transverse wave
- 16. The waves with the longest wavelengths in the electromagnetic spectrum
- 17. Part of a longitudinal wave area where the particles in the medium are close together
- 20. The highest part of a transverse wave
