Waves, Sound, and Light
Across
- 1. A transparent object with at least one curved side that causes light to change direction.
- 2. A material that allows most of the light that strikes it to pass through, but through which objects appear blurry.
- 3. A material that allows almost all of the light striking it to pass through, and through which objects can be seen clearly.
- 8. The change in direction of a wave as it changes speed while moving from one medium to another.
- 9. A wave that travels only through matter.
- 10. A material in which a wave travels.
- 12. A wave in which the disturbance is perpendicular to the direction the wave travels.
- 14. A material through which light does not pass.
- 16. The passage of a wave through a medium.
- 17. The distance between one point on a wave to the same point on the next wave.
Down
- 1. Causes the particles in a medium to move parallel to the direction that the wave travels.
- 4. The bouncing of a wave off a surface.
- 5. Color you see depends on the color the light reflects on.
- 6. A wave that is the number of times the pattern repeats in a given time.
- 7. A lens that is thicker in the middle than at the edges.
- 11. The change in direction of a wave when it travels by the edge of an object or through an opening.
- 13. A wave is the maximum distance that the wave moves from its rest position.
- 15. The transfer of energy by a wave to the medium through which it travels.
