|1.||the act or an instance of interfering|
|2.||physics the process in which two or more coherent waves combine to form a resultant wave in which the displacement at any point is the vector sum of the displacements of the individual waves. If the individual waves converge the resultant is a system of fringes. Two waves of equal or nearly equal intensity moving in opposite directions combine to form a standing wave|
|3.||Also called: radio interference any undesired signal that tends to interfere with the reception of radio waves|
|4.||aeronautics the effect on the flow pattern around a body of objects in the vicinity|
interference in·ter·fer·ence (ĭn'tər-fēr'əns)
The variation of wave amplitude that occurs when waves of the same or nearly the same frequency come together.
The condition in which infection of a cell by one virus prevents superinfection by another virus.
The condition in which superinfection by a second virus prevents effects that would result from infection by either virus alone, even though both viruses persist.
|interference (ĭn'tər-fîr'əns) Pronunciation Key
The disturbance that results when two waves come together at a single point in space; the disturbance is the sum of the contribution of each wave. For example, if two crests of identical waves arrive together, the net disturbance will be twice as large as each incoming wave; if the crest of one wave arrives with the trough of another, there will be no disturbance at all.
Note: One common example of interference is the appearance of dark bands when a light is viewed through a window screen.
