English: A light echo is a phenomenon observed in astronomy. Analogous to an echo of sound, a light echo is produced when a sudden flash or burst of light, such as that observed in novae, is reflected off a source and arrives at the viewer some time after the initial flash.
physical phenomenon caused by light reflected off surfaces distant from the source, and arriving at the observer with a delay relative to this distance;analogous to an echo of sound, it mostly only manifests itself over astronomical distances | |||||
