  1. 1. occurs when two or more waves overlap and form a new wave
  2. 4. material that absorbs or reflects all light and does not transmit any light
  3. 10. material that transmits and scatters light so that objects viewed through it appear blurry
  4. 11. image of a distant object produced by the refraction of light through air layers of different densities
  5. 12. light light that can contain more than one wavelength, travel in more than one direction, and has varying distances between the corresponding crests of the waves
  6. 15. distance between one point on a wave and the nearest point just like it
  7. 16. internal reflection the complete reflection of light at a boundary that occurs when light strikes at an angle greater than the critical angle, and light travels faster in the second medium than in the first medium
  8. 17. polarized light light whose magnetic field vibrates in only one direction
  9. 18. a colored material that is used to change the color of other substances
Down
  1. 2. material that transmits light without scattering so that objects are clearly visible through it
  2. 3. light light of only one wavelength that travels with its crests and troughs aligned
  3. 5. a transparent material that selectively transmits light
  4. 6. scanner device that reads reflected light intensity and converts it to digital signals
  5. 7. light light that is generated by using phosphors to convert ultraviolet radiation to visible light
  6. 8. of refraction property of a material indicating how much the speed of light is reduced in the material compared to the speed of light in a vacuum
  7. 9. a technique that produces a complete three-dimensional photographic image of an object, called a hologram
  8. 13. light light that is generated by heating a piece of metal until it glows
  9. 14. energy the sum of the kinetic energy and the potential energy of a system of particles
