How do bats avoid obstacles in their way, when in flight?

Hint:The above problem can be resolved by using the fundamentals of sound waves and their types. Moreover, the fact that the bats possess the ability to sense higher frequency sounds can be applied to come with the conclusion for the problem.

Complete step by step answer:
The bat possesses the remarkable ability to generate and detect the sound waves of very high frequency, usually up to or. When any obstacle is encountered in the bat's path, then the sound waves generated by the flying bats get reflected from any obstacle residing in front of it. Moreover, the hearing ability of the bats is even stronger than any other animal that they come to know the positions of obstacles just by hearing the echoes. In addition, they possess a special ability of vision even at night, which makes them fly safely without ongoing collision with the obstacles.

Note: In order to resolve the given problem, one must go through understanding the concept and fundamentals of the sound waves like frequency, amplitude, along with their applications. Moreover, try to learn additional information about the bats and their special abilities.
