  Interference  \In`ter*fer"ence\,  n.  [See  {Interfere}.] 
  1.  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 
 
  2.  (Physics)  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. 
 
  Note:  The  term  is  most  commonly  applied  to  light,  and  the 
  undulatory  theory  of  light  affords  the  proper 
  explanation  of  the  phenomena  which  are  considered  to  be 
  produced  by  the  superposition  of  waves,  and  are  thus 
  substantially  identical  in  their  origin  with  the 
  phenomena  of  heat,  sound,  waves  of  water,  and  the  like 
 
  3.  (Patent  Law)  The  act  or  state  of  interfering,  or  of 
  claiming  a  right  to  the  same  invention. 
 
  {Interference  figures}  (Optics),  the  figures  observed  when 
  certain  sections  of  crystallized  bodies  are  viewed  in 
  converging  polarized  light;  thus  a  section  of  a  uniaxial 
  crystal,  cut  normal  to  the  vertical  axis,  shows  a  series 
  of  concentric  colored  rings  with  a  single  black  cross;  -- 
  so  called  because  produced  by  the  interference  of  luminous 
  waves. 
 
  {Interference  fringe}.  (Optics)  See  {Fringe}.
