Across
- 3. waves that travel only through matter
- 5. passage of a wave through a medium
- 9. The maximum distance the wave moves from its rest position
- 10. A lens that is thicker in the middle than the edges
- 11. change in direction of a wave as it changes speed between mediums
- 12. Allows most light to pass through, but blurs objects through it
- 13. Transfer of energy by a wave to the medium through which it happens
- 16. a type of lens that has thicker edges than the middle
- 17. Change in direction of a wave when it travels by an edge/opening
- 18. distance between two points in the same place on different waves
- 19. The number of times a pattern of wavelengths repeats in a given time
Down
- 1. Causes the particles in a medium to move parallel to the direction the wave travels
- 2. Allows almost all light to pass through
- 4. bouncing of a wave off a surface
- 6. Doesn't let light pass through
- 7. the highest point in a wave
- 8. transparent object with at least one curved side
- 10. Can change what color an object appears as with reflection
- 14. a wave in which the disturbance is perpendicular to the direction the wave travels
- 15. a material in which a wave travels
