Detailed explanation-1: -Hint: Since, they use their hearing ability to produce ultrasonic waves with higher frequencies to locate their way and can travel miles by this smarter way, therefore, bats can fly in the dark.
Detailed explanation-2: -Echolocation is the use of sound waves and echoes to determine where objects are in space. Bats use echolocation to navigate and find food in the dark. To echolocate, bats send out sound waves from the mouth or nose. When the sound waves hit an object they produce echoes.
Detailed explanation-3: -Bats produce ultrasonic waves to detect obstacles in their path.
Detailed explanation-4: -The reason is that they produce ultrasonic sound as they fly. When this ultrasonic sound wave comes back after reflection from any object (or obstacle) in their way, they hear it and thus they detect the presence of the object in their way.
