$(b)$ Explain how ultrasound is used to clean spiral tubes and electronic components?
(N/A) The audible range of the average human ear is $20 \, Hz$ to $20,000 \, Hz$.
$(b)$ Ultrasound is used for cleaning by placing the objects (such as spiral tubes or electronic components) in a cleaning solution. When ultrasound waves are passed through the solution,the high-frequency vibrations cause the dust,grease,and dirt particles to detach from the surfaces. These particles then drop out,resulting in the thorough cleaning of the components.
