  1. 4. light Relating to electromagnetic radiation with wavelengths shorter than visible light.
  2. 5. Full range of frequencies of electromagnetic radiation
  3. 8. lens Spreads light rays apart
  4. 9. exterior angles Two exterior angles on opposite sides of a transversal which lie on different parallel lines.
  5. 11. Change in direction of wave propagation due to a change in its transmission medium.
  6. 12. Smallest unit of light
  7. 13. light Electromagnetic radiation with longer wavelengths than those of visible light, and is therefore invisible to the human eye.
  8. 15. lens Focuses light
Down
  1. 1. The action or process of magnifying something or being magnified, especially visually.
  2. 2. The rate at which a vibration occurs that constitutes a wave, either in a material (as in sound waves), or in an electromagnetic field (as in radio waves and light), usually measured per second.
  3. 3. The distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave.
  4. 6. angles The angles that occupy the same relative position at each intersection where a straight-line crosses two others.
  5. 7. Intersecting a system of lines.
  6. 10. The throwing back by a body or surface of light, heat, or sound without absorbing it.
  7. 14. A device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation
