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 A D B. A B C 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 Ꭰ
Two loudspeakers, 1.7 m apart, emit sound waves with the same frequency along the positive x-axis. Victor, standing on the axis to the right of the speakers, hears no sound. As the frequency is slowly tripled, Victor hears the sound go through the sequence loud-soft-loud-soft-loud before becoming quiet again. What was the original sound frequency? Assume room temperature of 20∘C.

Two loudspeakers emit sound waves of the same frequency along the x-axis. The amplitude of each wave is a. The sound intensity is minimum where speaker 2 is 10cm behind speaker 1. The intensity increases as speaker 2 is moved forward and first reaches minimum, with amplitude 2a, when it is 30cm in front of speaker 1. a. what is the wavelength of the sound
