Answer 2

Bats use the principle of echolocation to avoid hitting against obstacles in their path.

• The vision of the bat is very poor at the night time.
• So, to figure out the obstacles in the flight path, the bats are not dependent upon their visual observation.
• Instead of the visual observation they use a process called echolocation.
• In this process they generate a very high frequency sound and they process the reflected echo sound, to determine wether there is any obstacle or not.
