Hi friend_______,
Infrasonic waves:
★ These are sound waves with frequency below 20 Hz that cannot be heard by human ear.
★ Eg: Waves produced during earthquake, ocean waves, sound produced by whales, etc..
Ultrasonic waves:
★ These are sound waves with frequency greater than 20 kHz. Human ear cannot detect these waves.
★ Waves produced by bats is the best example for Ultrasonic waves.
