Define Doppler Effect

Doppler Effect (C.J. Doppler): The waves emitted by a moving object as received by an observer will be blue shifted (compressed) when approaching, redshifted (that is, elongated) if receding. This takes place both in sound and also electromagnetic phenomena, though it takes on dissimilar forms in each.
