in·ter·fer·ence  (ntr-fîrns)
n.
1.
a. The act or an instance of hindering, obstructing, or impeding.
b. Something that hinders, obstructs, or impedes.
2.
a. Sports Illegal obstruction or hindrance of an opposing player, such as hindrance of a receiver by a defender in football, hindrance of a fielder by a base runner in baseball, or checking a player not in possession of the puck in ice hockey.
b. Football The legal blocking of defensive tacklers to protect and make way for the ball carrier.
3. Physics The variation of wave amplitude that occurs when waves of the same or different frequency come together.
4. Electronics
a. The inhibition or prevention of clear reception of broadcast signals.
b. The distorted portion of a received signal.
5. The negative or distorting effect that new learning can have on previous learning or that previous learning can have on new learning.

inter·fer·ential (-f-rnshl) adj.

interference [ˌɪntəˈfɪərəns]
n
1. the act or an instance of interfering
2. (Physics / General Physics) 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. (Electronics & Computer Science / Telecommunications) Also called radio interference any undesired signal that tends to interfere with the reception of radio waves
4. (Engineering / Aeronautics) Aeronautics the effect on the flow pattern around a body of objects in the vicinity
interferential  [ˌɪntəfəˈrɛnʃəl] adj

interference  (ntr-fîrns)
1. The superposition of two or more waves propagating through a given region. Depending on how the peaks and troughs of the interacting waves coincide with each other, the resulting wave amplitude can be higher or smaller than the amplitudes of the individual waves. When two waves interact so that they rise and fall together more than half the time, the amplitude of the resulting wave is greater than that of the larger wave. This is called constructive interference. When two waves interact such that they rise and fall together less than half the time, the resulting amplitude is smaller than the amplitude of the stronger wave. This interference is called destructive interference. It is possible for two waves of the same magnitude to completely cancel out in destructive interference where their sum is always zero, that is, where their peaks and troughs are perfectly opposed. See more at wave.
2. In electronics, the distortion or interruption of one broadcast signal by others.
