In each of the four scenarios shown in the images, a large bat lets out a short burst of ultrasonic sound, which a smaller bat hears a moment later. If the large bat flies at 2.320 m/s and the small bat flies at 13.80 m/s, order the frequencies that the smaller bat detects in the four scenarios from highest to lowest. Assume that the speed of sound is 343.0 m/s. Highest frequency C D B. A B Lowest frequency Answer Bank In Scenario C, part of the large bat's signal reflects off the small bat and returns to the large bat, warning it of the smaller bat's presence. If the initial signal has a frequency of 66.70 kHz, what return frequency fr will the large bat detect? Calculate the final frequency to four significant figures. fr = Incorrect kHz D
