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