Ultrasound and Its Application
Ultrasound and its Applications: Ultrasounds are high frequency waves. They travel in straight line without bending around the corners. They can penetrate into matter to a large extent. Due to these properties, ultrasound is used in industry and in hospitals for medical purposes. Some of the important applications of ultrasound are given below:
1. In Cleaning Minute Parts of Machines: Ultrasound is used to clean parts located in hard-to-reach-places, such as spiral tubes, odd-shaped machines and electronic components, etc. Objects to be cleaned are placed in a cleaning solution and ultrasonic waves are sent into the solution. Due to their high frequency, the ultrasound waves stir up the solution, hence the particles of dust, grease and dirt vibrate too much, become loose, get detached from the object and fall into solution. The objects, thus get thoroughly cleaned.
