Bats produce high frequency (also known as ultrasonic) sound waves, which they use as a type of sonar, to locate insects in the air.
sound waves
ultrasonic sound waves
coz they can.
ultrasonic waves help bats to see at night
ultrasonic sound waves
Well bats use echo waves. These waves help them to know where everything is because bats are blind. See if you where standing there he would know your there with Eco waves with out actually seeing you
they use sound waves that mean somthing
In a cave at a frequency of 42,000 Hz
Ultrasonic sound waves
Ultrasounds are those sound waves that have a frequency that is higher than human hearing range that is above 20000 Hz. Bats produce these kinds of sound waves when they fly, this sound wave hits any obstacle(prey or enemy) in its path and gets reflected back to the bat (bcoz angle of incidence is always equal to angle of reflection). The bat senses the time taken for the sound wave to return and judges the distance of its prey or enemy. this help it to find its prey or enemy. Bats have this kind of adaptation because they donot have eyesight.
Sonar is a system that locates objects by transmitting sound waves and detecting the waves when they are reflected off of objects. Bats and many other animals, such as whales and dolphins, use natural sonar to navigate and capture
Some animals like bats and dolphins use sound to navigate. They do this by sending out sound waves. These bounce off of objects and come back to the animal. These returning sound waves are interpreted by the brain and create a kid of map for the animal.
