Dopplerov efekt sa v medic\u00edne pou\u017e\u00edva na ur\u010denie prietoku krvi v koron\u00e1rnych cievach a na diagnostiku zmien v cievach.

Dopplerov jav mal ve\u013ek\u00fd vplyv na astronomick\u00fd v\u00fdskum, najm\u00e4 v oblasti pohybu hviezd a kozmol\u00f3gie. \u0160t\u00fadiom pohybu svetla zo vzdialen\u00fdch hviezd sa astron\u00f3mom podarilo ur\u010di\u0165 r\u00fdchlos\u0165 a smer ich pohybu.
