Question
What are the uses of ultrasonic waves?
✓
Answer
Ultrasonic waves are used for the following purposes:
- They are used in SONAR for finding the range and direction of submarines.
- They are used for detecting the presence of cracks and other inhomogeneities in solids.
- They are used to kill the bacteria and hence for sterilising milk.
- They are used for cleaning the surface of solid.
