Intensity is a characteristic attributed to something or someone that presents itself in large proportions. Usually, this characteristic is related to the fact that something manifests or makes itself felt with force, vigor, something that is intense.
Example: "These photos of the fire could give us a sense of the intensity of the heat and fire on this day".
The intensity can also be attributed to characteristics that express the art, such as the volume of the sound or the vividness of the colors. For example, we can say that the sound is too loud or too quiet, or that a certain frame has very intense colors.
In Portuguese, specifically in the area of phonetics, intensity refers to the emission of phonemes or group of phonemes with greater strength in pronunciation than that of neighboring phonemes or group of phonemes. We also call it stressed syllable.
Also in Portuguese, the term is also used to characterize the adverbs that express this idea of intensity. Adverbs such as: quite, enough, enough, too much, more, less, a lot, how much, almost, so much and little, are examples of
intensity adverbs.See more about the adverbs.
The term intensity can still be replaced by synonyms such as: proportion, energy, strength, degree, and vehemence.
Intensity in Physics
The concept of intensity is most used in the field of Physics. In the field of electromagnetism, intensity is defined as the amount of electricity produced by a continuous electrical current during its unit of power.
She is represented by the intensity formula which is described below:
Where,
i - electric current intensity
Q - amount of electrical charge
Δt – time interval for passing the electric charge
In the International System of Units (SI), the electric current intensity is measured in amperes (A), resistance in Ohm (Ω) and electrical voltage (ddp) is measured in Volts (V).

Still in Physics, intensity can also be seen in the concepts of acoustics and waves, where it characterizes the vibration energy of the source that emits sound waves.
Intensity is a property of sound that is caused by the pressure the wave makes on the listener or on the instrument that measures it, such as an equalizer. The greater the sound pressure, the greater the intensity measured by the device.
