What is another word for Doppler Effect?
Pronunciation: [dˈɒpləɹ ɪfˈɛkt] (IPA) 
The Doppler Effect is a phenomenon that arises when there is a relative motion between the observer and the source of a wave. This effect can be described by different terms such as Doppler shift, Doppler frequency shift, or redshift (in case of light waves). Other terms that can be used as synonyms for the Doppler Effect are Doppler phase shift, Doppler time dilation, Doppler radar, or Doppler sonar (depending on the type of wave). The effect has various applications in different fields, from astronomy where it is used to measure the motion of celestial bodies, to medicine where it is used for ultrasound imaging. No matter what term is used to refer to the Doppler Effect, it remains a fundamental concept in wave propagation and motion detection.
