Across
  1. 5. A material through which visible light cannot pass.
  2. 6. The point on an optical axis at which all reflected or refracted light rays from incident rays that are parallel to the optical axis converge.
  3. 8. A material through which light passes but the light is scattered and does not transmit a clear image.
  4. 11. A model of light in which the endpoint represents the light’s source and the light travels in one direction.
  5. 15. An object that is visible because it reflects light from an external source.
  6. 17. An object that is producing visible light.
  7. 18. A curved mirror with the reflective side on the outside of the curve.
  8. 19. Light produced by objects that glow as a result of high temperature.
  9. 20. An image that forms at the point where converging rays of light intersect.
  10. 21. One of three colors (red, blue, green) of visible light that the human eye can sense.
  11. 23. A light ray approaching a surface; an incoming ray.
  12. 24. A curved mirror with the reflective side on the inside of the curve.
  13. 26. An image produced by diverging rays.
Down
  1. 1. A material through which light passes without scattering, transmitting a clear image.
  2. 2. A color of light that is produced when primary colors are mixed.
  3. 3. When a chemical reaction gives off energy in the form of light.
  4. 4. The process where a material glows for a longer period of time after absorbing energy.
  5. 6. Occurs when a material gives off visible light after absorbing electromagnetic energy.
  6. 7. The law that states that when a light ray reflects off a surface, the angle of the incident ray equals the angle of the reflected ray.
  7. 9. A color that forms because of pigments absorbing some wavelengths of light that strike an object.
  8. 10. A flat mirror.
  9. 12. A color that is produced by combining the wavelengths of different colors.
  10. 13. Light produced by some living things.
  11. 14. Reflection that occurs when a smooth surface reflects light rays in mostly the same direction. (regular reflection)
  12. 16. Reflection off a rough or uneven surface that reflects light rays in all directions.
  13. 22. The distance from the center of a lens or mirror to its focal point.
  14. 25. The ray that bounces off a surface.
