Question
(a) A bat uses ultrasound to find its way among trees. If this bat can detect echoes 1.00 ms apart, what minimum distance between objects can it detect? (b) Could this distance explain the difficulty that bats have finding an open door when they accidentally get into a house?
1. $0.343 \textrm{ m}$
2. Since doors are wider than 34 cm, this does not explain why bats have a difficult time finding the door to exit a house.
