A coyote can locate a sound source with good accuracy by comparing the arrival times of a sound wave at its two ears. Suppose a coyote is listening to a bird whistling at 1000 Hz . The bird is 2.5 m away, directly in front of the coyote’s right ear. The coyote’s ears are 15 cm apart. Part A) What is the difference in the arrival time of the sound at the left ear and the right ear? Hint: You...
