Answer 1

Hello mate,

Ultrasonic sound means we know that bat's are blind, they cannot see in dark caves, thus they produce an ultrasonic sound which when echoes back means there is a blockage in front of the cave and if it continues means the way is clear.

Answer 2

Ultrasound is sound waves with frequencies higher than the upper audible limit of human hearing(more than 20000 Hz).

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. Their sounds are reflected in the environment, hitting various objects and returning to the bat as echoes. The echo signals enable the bat to form a mental map of its surroundings.
