Summary
| Description |
English: Animation of waves emitted by an isotropic radiator, a coherent point source of radiation, represented by red dot. An isotropic radiator emits equal radiated power density in all directions in space. Isotropic sources are mathematical idealizations of real sources, used in optics, electromagnetics and acoustics. The amplitude of the waves is represented by lightness. As they travel away from the source, the waves decline in amplitude by the inverse of distance 1/r and in power by the inverse distance squared 1/r2, shown by the declining contrast of the wavefronts. This diagram only shows the waves in one plane through the source; actual isotropic sources would emit waves in three dimensions in space. 240x240 animated GIF consisting of 8 frames looped which repeats every 0.4 sec. Deutsch: Animation von Wellen, die von einem isotropen Strahler, einer kohärenten Punktstrahlungsquelle, ausgesendet werden, dargestellt durch einen roten Punkt. Ein isotroper Strahler strahlt in alle Richtungen im Raum eine gleich starke Strahlungsleistung ab. Isotrope Quellen sind mathematische Idealisierungen realer Quellen, die in der Optik, Elektromagnetik und Akustik verwendet werden. Die Amplitude der Wellen wird durch die Helligkeit dargestellt. Wenn sie sich von der Quelle wegbewegen, nimmt die Amplitude der Wellen um den Kehrwert der Entfernung 1/r ab und die Leistung um den Kehrwert der Entfernung im Quadrat 1/r2, was durch den abnehmenden Kontrast der Wellenfronten dargestellt wird. Dieses Diagramm zeigt die Wellen nur in einer Ebene durch die Quelle; tatsächliche isotrope Quellen würden Wellen in drei Dimensionen im Raum aussenden. 240 x 240 animiertes GIF, bestehend aus 8 Einzelbildern, die alle 0,4 Sekunden wiederholt werden. |
