Interference \In`ter*fer"ence\, n. [See Interfere.]
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.
-
(Physics) The mutual influence, under certain conditions, as from streams of light, or 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.
-
(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.

In physics, interference is a phenomenon in which two waves superpose to form a resultant wave of greater, lower, or the same amplitude. Interference usually refers to the interaction of waves that are correlated or coherent with each other, either because they come from the same source or because they have the same or nearly the same frequency. Interference effects can be observed with all types of waves, for example, light, radio, acoustic, surface water waves or matter waves.
In the game of chess, interference occurs when the line between an attacked piece and its defender is interrupted by sacrificially interposing a piece. It is a chess tactic which seldom arises, and is therefore often overlooked. Opportunities for interference are rare because the defended object must be more valuable than the sacrificed piece, and the interposition must itself represent a threat.
In baseball, interference occurs in situations in which a person illegally changes the course of play from what is expected. Interference might be committed by players on the offense, players not currently in the game, catchers, umpires, or spectators. Each type of interference is covered differently by the rules.
Interference may refer to:
Interference is a 1998 industrial album by Cubanate. In contrast to the band's previous releases, it incorporates drum and bass rhythms instead of regular dance beats, and the lyrics are more introspective and personal than what characterizes Cubanate's older material.
This album heavily focuses on use of the Amen Break as can be heard in It, Isolation, Hinterland, Other Voices, Voids.
The UK version of the album features two previously unreleased tracks, "Pleasure Kick" and "Ordinary Joe", recorded in 1996; accordingly, these tracks follow the more traditional Cubanate style.
Interference is an Irish band that formed in 1984. They are noteworthy for their live shows and for their powerful songwriting. Fergus O'Farrel's song 'Gold' was a feature in the Irish film ' Once' which won an Oscar for best song ( Falling Slowly, by Glen Hansard and Markéta Irglová ) and it is one of the major songs in the Broadway show of the same name, which cast performed the song during the 2012 Tony Awards where it won 8 awards.
Interference is an early sound film drama released in 1928 and starring William Powell and Evelyn Brent. This was Paramount Pictures' first ever full talking movie. It was also simultaneously filmed as a silent. The film was based on the play Interference, a Play in Three Acts by Roland Pertwee and Howard Dearden. When a first husband turns out not to be dead, blackmail leads to murder.
In communications and electronics, especially in telecommunications, interference is anything which modifies, or disrupts a signal as it travels along a channel between a source and a receiver. The term typically refers to the addition of unwanted signals to a useful signal. Common examples are:
- Electromagnetic interference (EMI)
- Co-channel interference (CCI), also known as crosstalk
- Adjacent-channel interference (ACI)
- Intersymbol interference (ISI)
- Inter-carrier interference (ICI), caused by doppler shift in OFDM modulation (multitone modulation).
- Common-mode interference (CMI)
- Conducted interference
Interference is typically but not always distinguished from noise, for example white thermal noise.
Radio resource management aims at reducing and controlling the co-channel and adjacent-channel interference.
Interference is the first album released by the Florida-based hard rock music group, Crease. This album was released in 1995, via DM Records. Interference earned Crease a Jammy Award nomination from JAM magazine for “Best Independent Release of the Year for the State for Florida”
Crossover interference is the term used to refer to the non-random placement of crossovers with respect to each other during meiosis. The term is attributed to Muller, who observed that one crossover "interferes with the coincident occurrence of another crossing over in the same pair of chromosomes, and I have accordingly termed this phenomenon ‘interference’."
Meiotic crossovers (COs) appear to be regulated to ensure that COs on the same chromosome are distributed far apart (crossover interference). In the nematode worm Caenorhabditis elegans, meiotic double-strand breaks (DSBs) outnumber COs. Thus not all DSBs are repaired by a recombination process(es) leading to COs. The RTEL-1 protein is required to prevent excess meiotic COs. In rtel-1 mutants meiotic CO recombination is significantly increased and crossover interference appears to be absent. RTEL1 likely acts by promoting synthesis-dependent strand annealing which results in non-crossover (NCO) recombinants instead of COs (see diagram). Normally, about half of all DSBs are converted into NCOs. RTEL-1 appears to enforce meiotic crossover interference by directing the repair of some DSBs towards NCOs rather than COs.
In humans, recombination rate increases with maternal age. Furthermore, placement of female recombination events appears to become increasingly deregulated with maternal age, with a larger fraction of events occurring within closer proximity to each other than would be expected under simple models of crossover interference.
