What is interference Short answer?
interference, in physics, the net effect of the combination of two or more wave trains moving on intersecting or coincident paths. The effect is that of the addition of the amplitudes of the individual waves at each point affected by more than one wave.

What is the difference between interference and decay?
Decay and interference theory differ in that Interference Theory has a second stimulus that impedes the retrieval of the first stimulus. Decay Theory is caused by time itself. Decay Theory is a passive method of forgetting as no interference is produced.
What are the two types of interference?
There are two types of interference: retroactive and proactive. Both are types of forgetting caused by a failure to retrieve information. With retroactive interference, new information hinders the ability to recall older information.
What does interference mean in science?
in′ter·fer·en′tial (-fə-rĕn′shəl) adj. interference. 2. ( 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.
What is the necessary condition for interference?
For sustained interference of light to occur, the following conditions must be met: Coherent sources of light are needed. Amplitudes and intensities must be nearly equal to produce sufficient contrast between maxima and minima. The source must be small enough that it can be considered a point source
What does interference mean?
Definition of interference. 1a : the act or process of interfering. b : something that interferes : obstruction. 2 : the mutual effect on meeting of two wave trains (as of light or sound) that constitutes alternating areas of increased and decreased amplitude (such as light and dark lines or louder and softer sound)
