Across
- 1. the group of colors (red, orange, yellow, green, blue, indigo, and violet) arranged in the order of their wavelengths; seen when white light passes through a prism and falls on a surface or when sunlight is scattered by water droplets to form a rainbow
- 3. cannot be seen
- 4. does not block light so that objects are entirely visible; clear
- 6. does not allow light through so objects on the opposite side cannot be seen; solid
- 8. able to be seen
- 10. a smooth or polished surface (ex: glass) that makes images by reflection
- 11. a point where something begins
- 13. to cause to separate (spread out) widely
- 14. visible wavelengths that make seeing possible
Down
- 2. light bounces back off a surface
- 4. lets some light through but objects are not clearly visible; frosted
- 5. a ray of light bends when it passes at an angle from one object into another
- 7. to take in something without giving it back
- 9. a transparent object that usually has three sides and bends light so that it breaks up into rainbow colors
- 12. the colors of the spectrum (rainbow) in order: red, orange, yellow, green, blue, indigo, violet
