Exercise:
Dolphins make use of ultrasonic pulses with frequencies of up to fO for their orientation. Calculate the frequency shift for a dolphin moving away from its shouting fri at vO.

Solution:
For an observer moving away from the sound source the received frequency is given by f_R ffracv_S-v_Ev_S It follows for the frequency shift Delta f f_R-f dfF -ftimesfracvvS df approx resultdfP The speed of sound in water can be looked up in the formula book.
