Across
- 3. liquids, and gases
- 4. change in direction of a wave when it travels by the edge of an object or through an opening
- 9. regions of a longitudinal wave where the particles are farthest apart
- 10. of a wave is the number of wavelengths that pass by a point each second
- 12. regions of a longitudinal wave where the particles in the medium are closest together.
- 14. lowest points on a transverse wave
- 16. the bouncing of a wave off a surface
- 17. a wave is a distance from one point on a wave to the same point on the next wave
- 19. Wave a wave that can travel through empty space and through matter
- 20. a disturbance that transfers energy from one place to another without transferring matter
- 21. of Reflection a wave is reflected from a surface, the angle of reflection is equal to the angle of incidence
Down
- 1. Wave: makes the particles in a medium move parallel to the direction that the wave travels
- 2. a wave is the maximum distance that the wave moves from its rest position
- 5. the passage of light through an object
- 6. the transfer of energy by a wave to the medium through which it travels
- 7. Wave a wave in which the disturbance is perpendicular to the direction the wave travels
- 8. highest points on a transverse wave
- 11. occurs when waves that overlap combine, forming a new wave
- 13. change in direction of a wave that occurs as the wave changes speed when moving from one medium to another
- 15. a material in which a wave travels
- 18. Wave a wave that can travel through
