What's the difference between interference and refraction?

Interference


Definition:

  • (n.) The act or state of interfering; as, the stoppage of a machine by the interference of some of its parts; a meddlesome interference in the business of others.
  • (n.) The mutual influence, under certain conditions, of two streams of light, or series of pulsations of sound, or, generally, two waves or vibrations of any kind, producing certain characteristic phenomena, as colored fringes, dark bands, or darkness, in the case of light, silence or increased intensity in sounds; neutralization or superposition of waves generally.
  • (n.) The act or state of interfering, or of claiming a right to the same invention.

Refraction


Definition:

  • (n.) The act of refracting, or the state of being refracted.
  • (n.) The change in the direction of ray of light, heat, or the like, when it enters obliquely a medium of a different density from that through which it has previously moved.
  • (n.) The change in the direction of a ray of light, and, consequently, in the apparent position of a heavenly body from which it emanates, arising from its passage through the earth's atmosphere; -- hence distinguished as atmospheric refraction, or astronomical refraction.
  • (n.) The correction which is to be deducted from the apparent altitude of a heavenly body on account of atmospheric refraction, in order to obtain the true altitude.

Example Sentences:
