The concept of spaciousness has several uses. The first meaning mentioned in the dictionary prepared by the Royal Spanish Academy (RAE) refers to the widening, stretching or lengthening of something.

According to DigoPaul, amplitude, in this way, can refer to the ability of a person to understand, tolerate, accept or value different issues. For example: "We need teachers with greater mental amplitude, who are willing to understand the new habits of children", "The manager of the company has demonstrated his broad criteria when evaluating the different situations of employees", " This man lacks breadth: he does not accept that society has changed in recent years. ”

In this context it can be understood as a synonym of mental openness, since it refers to the capacity that each person has to accept the coexistence of different concepts or ideas, without canceling each other out. In the examples in the previous paragraph, the need for this predisposition in the teaching body is mentioned, something fundamental for children to grow up in an environment free of prejudices, which allows them to know themselves and enjoy their differences, instead of suffering from they.

On the other hand, there is the closure, which can be defined as the impossibility of understanding a concept, either due to prejudice or ignorance. This characteristic of certain people who refuse to open also known by the name of obstinacy or stubbornness, and one of the worst enemies of cultural progress.

Individuals who lack mental amplitude reject those they consider different, since they do not understand that they are also different in the eyes of others. The origin of this contempt is usually a very deep fear, probably to be treated in the way that they themselves adopt, and this makes it very contradictory. Thanks to the amplitude comes change, another of the enemies of closed people, and this leads to the growth and evolution of society.

The idea of amplitude is also used with respect to a difference that can be registered numerically between two given values: "The local team widely outpaced Spain and qualified for the next round of the tournament", "Political analysts were surprised by the amplitude of the defeat of the oficialismo in the last elections ”, “ This region is characterized by the thermal amplitude: the days are hot, while at night very low temperatures are registered ”.

It is important to note that the concept of amplitude, when used to point out the difference between two numerical values, is relative. This is because certain parameters, specific to each field, must be taken into account in order to determine if the resulting number is large.

When studying the temperature changes of a region between the hours of the day and the night, to continue with one of the previous examples, a difference of 1 degree centigrade cannot be taken as wide, but rather values ​​higher than 10 are necessary. so that they generate a considerable impact. On the other hand, in a calculation in which the minimum is 0 and the maximum is 1, oscillations of 0.8 do speak of amplitude. We must remember that the units of measurement are arbitrary, since they are invented by the human being to study natural phenomena.

In the field of physics, amplitude is called the variation that exists in a magnitude that changes over time. The magnitude can be calculated in an electromagnetic signal or in wave or oscillatory movements.

It is known as amplitude modulation to a technique that, in the communication of electronic type, is to transmit information via a transverse wave whose amplitude varies according to the data sent.
