- 1. A materiel that allow all the light that strikes thought and the objects can be seen clearly
- 3. The Spreading of waves around obst
- 9. is the bouncing of a wave off a surface
- 10. A material through which light does not go through
- 13. form of a curling top of a wave
- 14. The matter that can transmit some energy to the other side of the barrier and it will continue has a wave
- 16. lens A lens that is thicker in the middle that at the edge
- 18. is a wave that travels only through matter
- 19. Causes the particles in a medium to move parallel to the direction that a wave travels
Down
- 2. The change in direction of a wave as it changes speed while moving from one medium to another
- 4. The number of times the pattern repeats in a given time
- 5. Waves where the particle motion is in the same direction in which is prorogation
- 6. A material in which a wave travels
- 7. Filters that when you see a color depends on the color
- 8. is the maximum distance that a wave can travel its rest position
- 11. Is the transfer of energy by a wave to the medium through which it travels
- 12. Is a transparent object with a least one curved side that causes light to change direction
- 15. Material that allows almost all of the light that strikes it to pass through
- 17. The distance between one point on a wave to the same point on the next wave
