What Does interference Mean
The first thing we are going to do to discover the meaning of the term interference is to know its etymological origin. In this case, we have to state that it derives from English, specifically from the word “interference”. Exactly that is the result of the union of two different parts: the verb “interfere”, which can be translated as “interfere”, and the suffix “-ence”.
This is the name of the act and the result of interfering : altering the development of something, crossing.
Among the many words that can be used synonymously with interference are interruption, nuisance, interference, crossing, obstacle, cutoff, or intrusion. On the contrary, among its antonyms we come across terms such as resumption or discretion.
In the field of physics , interference is called the action that the waves perform reciprocally, causing the cancellation, growth or decline of the wave motion depending on the case. When an interference occurs, two or more waves end up overlapping and giving rise to the appearance of a new wave that may have less, equal or greater amplitude.
Interference can be generated in any kind of wave . Sound waves and light waves, for example, can interfere.
In the field of communication , an interference supposes a modification of the message while it is transmitted through a channel. Suppose two people are talking on a cell phone (mobile). If there is an interference in the signals, it is possible that each individual hears the voice of the interlocutor choked, making conversation difficult.
Specifically, in the field of communication we have to point out that there are two types of interference:
-Constructive interference, which is what increases the intensity of two waves. Exactly this occurs when there are two waves that have the same or similar frequency and the crest of one wave is superimposed on the crest of the other. This allows their effects to come together and, therefore, give rise to a wave of greater amplitude.
-Destructive interference, meanwhile, is responsible for reducing the intensity of two waves. Specifically, what happens is that the crest of one wave overlaps the valley of the other wave and that results in their cancellation.
In the field of Psychology, on the other hand, there is the Theory of Interference. This is what comes to expose is that forgetting is the result of the interference of some memories on others.
The concept of interference also appears in sport . In American football , interference is a movement that a player makes to obstruct the progress of an opponent with his body. In ice hockey , interference is considered a foul: a player makes it impossible for another athlete who does not have the puck to move.
Lastly, the idea of humanitarian interference or interference refers to the intervention of international organizations and / or States in a sovereign country through the use of arms. The interfered nation does not consent to this action, which aims to protect the civilian population in an emergency (genocide, civil war, etc.).
