The bat emits a high picked squeek and picks up any of the sound waves that bounce back off objects - it works the same way as sonar.
Is cyclic sound pressure with a frequency greater than the upper limit of human hearing. Ultrasound imaging is a common diagnostic medical procedure that uses high-frequency sound waves to produce dynamic images (sonograms) of organs, tissues, or blood flow inside the body.
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.
It is called echolocation.
Studies have proven that ultrasonic sound does not reverberate. This means that once the ultrasonic sound hits a surface, it disappears. Any animal that is living in any kind of crevice, such as a bat, they won't even hear the sound at all. ADDED. That's not correct: you have misunderstood "the studies" and the basics of sound. Ultrasound will not normally give rise to reverberation because as its frequency rises its absorption losses through the air rise, on top of the attenuation by distance. Some surfaces will absorb sound, but generally ultrasound is easily reflected from any suitable surface, and the bat will hear a sound within its own hearing frequency-range. This is how bats navigate and hunt!
The sound which is over 20 000 Hz is called ultrasonic. It can't be heard by human ears. It can be heard and produce by some of the animals and mammals e.g.-Dolphin,bat etc. The sound which is less then 20 Hz is called infrasonic. The sound is divided into these two parts.
Usually its actually echolocation . But they use to hunt for prey ( their food ) .
Bats, as one may know, are blind, and to find it's prey (food) it causes ultrasound, which is invisible of course, imagine a wave, in the ocean, the waves hit something, and the wave is directed back to where it came from, and anything the wave does not hit, continues. That is how bats use ultrasound to hunt.
they listen out for sounds and the ultrasound hits the prey and comes back to the bat
It depends on how many of the prey you are referring to. Singular prey - the bat's prey is an insect Multiple prey - the bat's prey are all flying away
The bat uses their echoes of their cries to know where the prey is.
Usually all bats catch their prey through echo-location.Some bats like the fruit bat can see in light as clearly as we do.Though no bat has been found yet that can see in the dark like cats.But the eyesight of the fruit bat is wasted as all bats are nocturnal mammals.

Bats use echo location, they track down sounds of prey by their sound waves.
Ultrasound sound waves
The bat-eared fox is predominantly an insectivorethat uses its large ears to locate its prey. 80–90% of their diet is harvester termites (Hodotermes mossambicus).
No it is not and its a Predator.
Disk-winged bats use echolocation to find their prey. The bat uses a high pitched sound that is reflected off of objects in its surroundings.
Yes. Some have even developed a method for detecting when a bat uses echolocation in order to avoid becoming its prey.
