Question

Bats have no eyes still they can ascertain distances, directions, nature and size of the objects. Explain why.

Answer 1

Bats can produce ultraviolet sounds which we can't hear because it's frequency is much greater than the frequency that we hear they so when they produce it , if there is an object it strikes back and comes to the bat again but if there is no object it goes away in this way bats fly in night .

Answer 2

Hey there!

Bats have special types of wings. When they fly they produce ultrasonic waves. These waves are received by the ears of bat after they have been reflected by the object. The ears of the bat are so sensitive and trained that they not only get information of distance of the obstacle but also that of the nature of the reflecting surface.
