  1. 1. the transfer of energy carried by light waves to particles of matter
  2. 2. the bending of waves around barriers or through openings
  3. 3. wave that can travel through space or matter and consists of changing electric and magnetic fields
  4. 6. EM waves with long wavelengths and low frequencies
  5. 8. the emission of energy in the form of EM waves
  6. 9. bending of a wave as it passes at an angle from one medium to another
  7. 10. EM waves that are between radio waves and infrared waves in the electromagnetic spectrum
  8. 12. states that the angle of incidence is equal to the angle of reflection
  9. 13. occurs when light or any other wave bounces off an object
  10. 14. The angle between the incidence and the normal
  11. 15. a tiny packet of energy that is released by the electron that moves to a lower energy level in an atom
  12. 17. EM waves with very high energy and no mass or charge; they are emitted by the nucleus of a radioactive atom
  13. 19. transmits light but also scatters the light it passes through the matter
