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
Bats produce high frequency (also known as ultrasonic) sound waves, which they use as a type of sonar, to locate insects in the air.
Bats produce ultrasonic sound waves to sense obstacles in their environment. These waves bounce back, allowing bats to navigate and locate objects in the dark.
Bats use high-frequency sound waves, called echolocation, to sense obstacles in their environment. They emit these sound waves which bounce off objects, allowing the bat to receive and interpret the echoes to navigate and locate prey.
Bats use high-frequency ultrasonic sound waves for echolocation, while whales use lower-frequency sound waves called infrasound. Both species emit these sound waves and listen for the echoes that bounce back off objects to navigate and locate prey.
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
ultrasonic sound waves
Bats rely on the property of echolocation in waves to navigate and locate prey. They emit high-frequency sound waves that bounce off objects and return as echoes, allowing bats to perceive their surroundings in the dark. This helps them "see" by using sound instead of light.
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.
None ! Some animals such as bats, use ultra-sonic sound to locate prey, and 'see' in the dark.
Bats - and dolphins. They both use sound waves to find food.
