  1.  inverse square model
 
This is an important principle in photometry and in the sutdy of gravitational, electrical, and magnetic fields.
  1.  Level one shows the first distance from the origin, therefore 1^2 = 1 square area.
  2. Level two is two times the distance of level 1 from the origin, therefore 2^2 = 4 squares of area.
  3. Level three is three times the distance of level 1 from the origin, therefore 3^2 = 9 squares of area.
  4. After showing the above, note that intensity (of the origin’s energy) diminishes by the inverse of distance squared.
