  1. 1. wave, vibrate in the direction of the line of advance of the wave
  2. 3. instrument that makes a record of
  3. 6. of reflection,the angle made by a reflected ray with a perpendicular to the reflecting surface.
  4. 8. distance between two crest or trough
  5. 10. wave,combination of two waves moving in opposite directions
  6. 12. wave, P waves are the fastest seismic waves and can move through solid, liquid, or gas

  11. 23. when one object vibrating at the same natural frequency of a second object forces that second object into vibrational motion
  12. 25. something that moves energy
  13. 28. of incidence,he angle which an incident line or ray makes with a perpendicular to the surface
  14. 30. he process by which a beam of light or other system of waves is spread out
