Across
- 2. passage of a wave through a medium
- 3. Maximum distance that the wave is from its rest position
- 9. that is thicker at the edges than the middle
- 10. material in which a wave travels is called
- 12. allows most a light to pass through and objects can be seen clearly
- 13. wave that travels only through matter
- 16. material through which light doesn't pass through
- 17. The color you see depends on the color of light that objects reflects
- 20. most light to pass through nut appear blurry
Down
- 1. Particle motion is in the same direction in which the wave is propagating
- 4. Change in direction of a wave when it travels by the edge of an object
- 5. is a wave in which the disturbance is perpendicular to the direction the wave travels
- 6. distance between one point on a wave to the same point on the next wave
- 7. flat reflective surface
- 8. causes the particles in a medium to move parallel to the direction that the wave travels
- 11. number of times the pattern repeats in a given time
- 14. Lens that is thicker in the middle than at the edges
- 15. Transfer of energy by a wave to a medium through which it travels
- 18. change of direction of a wave when it changes speed while moving from one medium to another
- 19. transparent objects with at least 1 curved side that causes light to change direction
