Question

Which of the following frequencies of sounds, bats can produce and hear?

• A. ultrasonic
• B. infrasonic
• C. both A & B
• D. cant say

Answer 1

The correct option is A ultrasonic

Bats find their prey in the dark using the navigation system called echolocation. Bats emit sounds at typically 2 or 3 times higher pitch than we can hear. Sounds above human hearing are usually called ultrasonic.
The echolocation sound has an extremely high pitch so high that it is beyond the human hearing range. But the sound behaves the same way as the sound of your shout. It travels through the air as a wave, and the energy of this wave bounces off any object it comes across. A bat emits a sound wave and listens carefully to the echoes that return to it. Hence, Bats can produce and hear ultrasonic sound.
