It is a word that has a diversity of uses as wide as the languages in which it is pronounced, as well as in the different areas of scientific study, as well as in those of colloquial use it has a certain context. In the branch of physics, intensity is the energy that is transferred per unit area, which is transmitted along an imaginary area perpendicular to the direction of propagation. Intensity can be applied in other circumstances where energy is transferred.
For example, one could calculate the intensity of the kinetic energy propagated in the drops of water that come out of a garden watering mechanism. The intensity can be calculated from the energy density (energy per unit volume) of a point in the space and multiplying by the speed at which the energy moves. The resulting vector is the units of energy divided by the area. In contrast, the word "intensity" when used in colloquial language, is synonymous with "strength", "magnitude", "level" or "amplitude" as for example: "On summer days the heat is so intense that people tend to take several baths a day in order to cool off . "
This word can also be associated within contexts where scenarios are something that denotes power, is present in politics, wrestling, is, etc. In photometry and radiometry, the word "intensity" has another meaning: it is the luminosity or radiant energy per unit solid angle. Spectral arrogance is another term used to refer to intensity, especially in the area of astronomy and astrophysics and to also denote heat transfer.
