  1. 4. a force that resists the relative motion of two surfaces that are in contact
  2. 5. a region of space in which each point is subject to a non-contact force
  3. 9. a standing wave with a frequency equal to an integer multiple of the fundamental frequency
  4. 11. the addition of overlapping waves in the same medium
  5. 12. the splitting of white light into its constituent colours due to different refractive indices for different frequencies
