  4. 8. is the bending of waves around barriers or through openings
  5. 9. the entire range of EM waves
  6. 10. frequency modulation
  7. 11. is a wave interaction that occurs when two or more waves overlap
  8. 14. occurs when light or any other wave bounces off an object
  9. 15. matter through which visible light is easily transmitted
  10. 18. a wave that that can travel through space or matter and consists of changing electric magnetic fields
  11. 20. a material that gives a substance its color by absorbing some colors of light and reflecting others
  12. 21. matter that does not transmit any light
  13. 22. matter transmits light but also scatters the light as it passes through the matter
