Web10 Important Properties of Ultrasonic Waves Property 1: Ultrasonic waves vibrate at a frequency greater than the audible range for humans (20 kilohertz). Property 2: They have smaller wavelengths. As a result, their penetrating power is high. Property 3: They cannot travel through vacuum. WebUltrasonic waves detect an object in the same way as Radar does it. Ultrasonic uses the sound waves, and Radar uses radio waves. When ultrasonic pulse signal is targeted towards an object, it is reflected by the object and echo returns to the sender. The time travelled by the ultrasonic pulse is calculated, and the distance of the object is found.
