intensitats
Intensitats is the plural of intensitat, a term used in Catalan to describe the magnitude of a physical quantity that measures the strength, concentration, or rate of energy flow in space. The concept is used across disciplines such as optics, acoustics, and spectroscopy to express how much of something passes through a given surface or travels in a given direction, often per unit area or per unit solid angle.
In photometry and radiometry, radiant intensity I is the power per unit solid angle emitted by a
Irradiance E describes the radiant power per unit area incident on a surface (W/m^2). The relation between
In acoustics, sound intensity is the mean energy flow per unit area (W/m^2) and relates to pressure
In spectroscopy, intensitats d’emissió o absorció indicate the strength of a spectral feature, often proportional to
Measurement relies on instruments such as photometers, radiometers, spectrometers, and sound level meters. Understanding intensitats supports
