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