Time Frames for Negative Information. Late payments are black marks that normally stay on a credit report for 7 years.

Wiktionary (0.00 / 0 votes) Rate this definition: Doppler effect (Noun). The apparent change in frequency or wavelength of a wave that is perceived by an observer moving relative to the source of the waves. Origin: From Johann Christian Andreas Doppler, the scientist who first proposed this effect.
If it's moving away from you it's wavelength will be increased. Since most objects in space that we study are moving and also emit light, we can tell if they're moving toward or away from us by measuring their wavelengths. There's an excellent animated demonstration of the doppler effect at this website ==>http://www.astro.ubc.ca/~scharein/app...
