a bat can find its way in the dark . how?

Answer 1

A bat sends ultrasonic chirps and figures out from the returned echoes where things are.

Answer 2

The bat emits a loud sound (represented by the orange lines) that travels out into the environment until it hits something (such as the insect in this picture).

When the sound hits, some is reflected back as an echo (the gray lines in the figure). The bat can hear the echo and use that to tell a lot about the obstacle, such as how far away it is and some fine details such as its size and shape.

This allows many of these bats to capture flying insects by hunting them down like a radar-guided missile.

These types of bats (the Microchiroptera) tend to have large ears and small eyes.

----> While vision is not as important to these bats as it is to the Megachiroptera, these bats can see, so the saying "blind as a bat" is a myth!



A bat uses Echolocation

Answer 3

The bats are having excellent mechanism of sending sonars means some kind of sounds in the form of waves. When the sonar touches some thing it immediately returns to the bat and thus it finds it's way as well as the food in dark.

Answer 4

A bat finds it by a simple method called echolocation. this method is used by animals such as dolphins and whales also.
Echolocation works somewhat like a sonar made by an animal. Ranging is most certainly done by measuring the time delay between the animal's own vocalization and any echoes that return from the environment. Unlike some sonar which relies on an extremely narrow beam to localize a target, animal echolocation relies on multiple receivers, the two ears, to perform localization.

Answer 5

Bats can't see but the find their way in darkness with help of sound frequency 20Hz to 200Hz( in b/w these Hertz only human beings can hear not above or below) But Bats can hear all kinds of sounds
For eg: In the night times when bats fly they normal shout when their is a object in path they are going that sound wave goes and hits that object and returns back ( if at all their is any object) and they can identify that the object is their in that particular way so they save themselves from hitting that object. They normal come out side in the night times only .

Answer 6

bats use a system called echolocation. this is where a bat sends out high-pitched squeaks(to high for humans to hear), and listens for them to echo back. if the bat does hear an echo, that means something is in its path, the echo creates an image in the bat's brain that tells it what is in front of it. it also tells the bat how far away the object is, depending on how long it took for the echo to return. it works something like a modern radar or sonar system on a ship. echo location is also used by animals like dolphins and whales.

Answer 7

in simple language-
a bat lets out a high-pitch scream while flying in the dark.
the noise hits an object in the bat's path and is reflected back-or echoed back-to the bat
the bat hears the echo
according to the time taken to receive the echo back, the bat estimates the distance of the object
according to the variance in the pitch of the echo, the bat figures out the shape and size of the object
the bat responds to this as the bat's brain creates a kind of sound-picture in it's mind.
the process is called echo-location.
thank you. i enjoyed answering that one!

Answer 8

It's called echolocation. Basically, bats emit a sound, and the sound travels outward from them. When it bumps into something, it reflects back to them as an echo, and from the sound of the echo, they can tell all sorts of information about the item, including it's size, and which way it is moving if it is in motion. Essentially, it allows them to "see" in the dark.

Answer 9

Strange as it might sound, sonar. Yes, the very same thing subs use. They emit sounds and can calculate pretty accurately how far away their prey is just by how long the reverberation of the sounds they emited return back to them.

Pretty amazing actually and deadfully acurate for the demise of the prey. Studies continue to understand exactly just how this sense with bats actually functions. Great Q!

Answer 10

Bats use Sonar or sound waves to find their way. They send signals and if there is an object in front the sound waves will get reflected and thus they go about places
