  2. 6. wave a disturbance or vibration in matter
  3. 7. an electromagnetic wave with a wavelength in the range 0.001–0.3 m, shorter than that of a normal radio wave but longer than those of infrared radiation.
  4. 11. forces a type of physical interaction that occurs between electrically charged particles
  5. 12. the degree or intensity of heat present in a substance
