What's the difference between diffusion and reflection?

Diffusion


Definition:

  • (n.) The act of diffusing, or the state of being diffused; a spreading; extension; dissemination; circulation; dispersion.
  • (n.) The act of passing by osmosis through animal membranes, as in the distribution of poisons, gases, etc., through the body. Unlike absorption, diffusion may go on after death, that is, after the blood ceases to circulate.

Reflection


Definition:

  • (n.) The act of reflecting, or turning or sending back, or the state of being reflected.
  • (n.) The return of rays, beams, sound, or the like, from a surface. See Angle of reflection, below.
  • (n.) The reverting of the mind to that which has already occupied it; continued consideration; meditation; contemplation; hence, also, that operation or power of the mind by which it is conscious of its own acts or states; the capacity for judging rationally, especially in view of a moral rule or standard.

  • (n.) Censure; reproach cast.
  • (n.) The transference of an excitement from one nerve fiber to another by means of the nerve cells, as in reflex action. See Reflex action, under Reflex.

Example Sentences:
