What is an ultrasonic sound? How does it help the bat to catch its prey at night?
Answers
Ultrasound is sound waves with frequencies higher than the upper audible limit of human hearing.
At night the bat uses its hearing to navigate its way to prey. Bats catch insects continuously using echolocation, an advanced navigation system. The bat emits ultrasonic waves with very high frequencies. Its calls are pitched at 20-100 kilohertz, a frequency that is too high-pitched for humans to hear naturally
Ultrasonic sound is the sound which is above 20kHz.
Bats catch insects with the help of an advanced navigation system known as echolocation. They are known to emit high-frequency ultrasonic wavespitched at 20-100KHz. This is too high for the natural hearing of humans. These sounds get reflected when it hits different objects and reverts to thebats as echoes.
