Web11 Jun 2024 · Ultrasonic waves can penetrate liquid, solid and can even penetrate tens of meters depth in opaque solid. When the wave contacts with impurities or the interface, there will be a significant reflection to form a reflection echo, and the Doppler effect will occur when it touches the moving object. Therefore, ultrasonic detection is widely used ...

Web7 Nov 2024 · The distance covered by the wave at a given time period. In ultrasonic testing, the speed is measured in Meter per second (m/sec). The speed of a wave is determined by the type of wave and the nature of the medium. As a wave enters a different medium/material, the wave’s speed changes. Waves travel at different speeds in different … Webultrasonics, vibrations of frequencies greater than the upper limit of the audible range for humans—that is, greater than about 20 kilohertz. The term sonic is applied to ultrasound …
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.
