Question

Is ultrasonic and supersonic waves are same??

Give 3 uses of supersonic waves???

Answer 1

Hi hope this helps you..
They are different things. Supersonic is used for objects travelling at a speed greater than the speed of sound of the medium. Ultrasonic is used for a sound wave having frequency exceeding the upper limit of the human audible range. Humans can hear sounds beteeen frequencies 20 Hz to 20 kHz, so sound waves with a frequency greater than 20 kHz are ultrasonic waves.


Uses of Ultrasonic Waves

In the Field of Communication
Few animals such as bats and frogs have the ability to use ultrasound to communicate with each other. Bats emit high pitched sound of short wavelength in order to navigate. These waves hit the surrounding and bounce back allowing bats to get an exact map of the surrounding. These bats communicate with each other with ease, thanks to the ultrasound waves.

Ultrasonic Cleaning
One of the many applications of ultrasonic sound waves is ultrasonic cleaning. It is used to get rid of impurity from certain devices that are absorbed in aqueous solution. Materials like glass, metals, and ceramics can be cleaned using this and in addition to that, ultrasonic waves can be used to remove grease, oil and dirt. Ultrasonic sound waves are also used in industries in order to get rid of chips and oil from machinery and other industrial equipments. It is also used to get rid of sludge and lubricant from the apparatus of aircrafts and automobiles.



Ultrasonic Welding
Ultrasonic sound waves are also used for the purpose of welding plastic. High frequency ultrasonic vibrations are used to weld couple of parts of the plastic. However, this welding process is very well programmed and has time and frequency already programmed into the welding machine and computer carry out each and every step of the welding process.
