ultrasonic waves
Beyond human hearing
Ultrasonic waves are sound waves at frequencies above the range of human hearing—roughly 20,000 hertz and higher.
They have applications in medical imaging (ultrasound scans), industrial cleaning, sonar, and measuring distances.
Bats and dolphins use ultrasonic waves for echolocation.
The technician used ultrasonic waves to detect cracks in the metal.
