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