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