WebNov 7, 2024 · Doppler Effect is a phenomenon that is observed when the source of the waves moves with respect to an observer. It is a characteristic of sound waves in general. The Doppler Effect describes the apparent shift in sound frequency when the observer and the medium are both moving in the same direction. It is determined by three factors: the … WebUnderwater ultrasonic devices using the Doppler effect generally presuppose that the speed of sound is uniform in a propagation medium. Actually, however, the speed of sound in the sea varies with water depth, so that the assumption of such uniform speed has the potential to cause measurement errors …
