  1. 2. A phenomenon that occurs when a wave or object bounces off an interface or another object
  2. 4. How fast a wave is moving
  3. 7. The type of wave where the particles move only perpendicular to the wave direction
  4. 8. The SI unit of electrical resistance in a circuit transmitting a current of one ampere when subjected to a potential difference of one volt
  5. 10. A measure of the amount of electric charge in motion per unit of time
  6. 11. A particle of electric charge that is negative and found in all atoms and is the primary carrier in solids
  7. 13. A disturbance or vibration that transfers energy progressively from one point to another in a medium
