  4. 11. What do like charges do?
  5. 16. Occurs when waves that overlap combine, forming a new wave.
  6. 17. Waves in which the motion of the particles are perpendicular to the motion of the wave is called
  7. 18. a map of a circuit
  8. 20. The bouncing of a wave off a surface.
  9. 22. The change in direction of a wave that occurs as the wave changes speed when moving from one medium to another.

  4. 4. Number of wave Length that passes a point in a given time interval
  5. 6. a circuit containing a source of energy and at least one conductor. It may also include a switch, which opens or closes a gap in the circuit.
  6. 9. The greatest distance that particles displaced form their normal resting position is called

  13. 20. a material that resists the flow of an electric charge
  14. 21. High point of a transverse wave
  15. 23. When a wave is reflected from a surface, the angle of reflection is equal to the angle of incidence.
  16. 26. a material used to reduce or prevent the transfer of electricity
  17. 28. Low point of a traverse wave
  18. 29. controls the flow of charges by closing or opening a gap in the circuit
