1. The change in direction of a wave as it changes speed while movine from one medium to another medium.
3. These lenses are thicker in the middle than the edges.
4. The color of an object that absorbs all wavelengths of light and reflects not light.
7. When light travels in one direction then are made to travel in many directions.
9. Where an image is formed when light enters the eye.
10. The type of cells that are sensitive to low light levels and allow people to see in dim light.
12. When a wave is reflected from a surface, the angle of reflection is eincidencehe angle of incidnece.
14. How light wave wavelengths are measured.

2. A material that allows almost all light to pass through and objects can be seen clearly.
5. Material that absorbs light, which you cannot see through and light does not pass.
6. The distance along the optical axis between the lens and the focal point.
8. How the mixture changes as you add each color of pigment because all colors are absorbed.
11. A type of mirror that curves inward.
13. What type of energy is carried by electromagnetic waves?
