emittiertes

Emittiertes is the participle form of the German verb emittieren and is used as an adjective meaning "emitted" or "emitted energy or particles." It describes phenomena that originate at a source and propagate away, such as electromagnetic radiation, particles, or acoustic signals. The term appears in physics, engineering, and related fields to specify what a source has released.

In physics, emittiertes refers to radiation, particles, or energy released by a system. Emission can be spontaneous or stimulated, and it is closely linked to transitions between energy states in atoms or molecules. This leads to characteristic spectra, known as emissionsspektren, which reveal information about composition and conditions. Thermal emission describes radiation drawn from objects due to temperature, with real surfaces characterized by an emissivity between 0 and 1.

In spectroscopy and astronomy, das emittierte Spektrum is used to analyze light from a source to determine chemical makeup, temperature, density, and motion. Emitted light contrasts with reflected or transmitted light, which does not originate from the source itself. In engineering, emittiertes energy is a key consideration in lighting, lasers, sensors, and radiative heat transfer.

Measurements of emittiertes radiation involve its intensity, spectral distribution I(λ), total power, and angular or polarization properties. Related terms include Emission (the process), Emissivität (emissivity), and emissiv as used in technical contexts. The concept serves as a foundation across disciplines for understanding how sources release energy and how such energy is observed and quantified.
