Question

To detect the obstacles in their path, bats produce :

• A. infrasonic waves
• B. ultrasonic waves
• C. electromagnetic waves
• D. radio waves

Answer 1

Answer: (B)

ultrasonic waves

Echolocation- broadly described as seeing with sound.

Bats use sound waves and echoes to determines where objects are in space.

Bats navigate their territory and seek out prey by emitting sound waves or bat calls ) (a variety of chirps and squeaks)

Narrowband calls (constant frequency or CF calls) identify potential prey

Broadband calls (Frequency Modulation or FM calls) scan the landscape.

Bats use ultrasonic sound for navigation. Their ability to catch flying insects while flying full speed in pitch darkness is astounding. Their sophisticated echolocation permits them to distinguish between a moth (supper) and a falling leaf.
