DEFINITION:Sounds of frequency higher then 20,000Hz which are inaudible to human ear,can be produced and are utilized in many useful ways.Such sounds are called ultrasonics.
PROPERTIES:
1:In medical feilds utrasonics waves are being used to diagnose and treat different ailments.
2:These waves are also reflected by differently by different organs,tissues,benign or malignant tumors

What is the properties of ultrasonic sound waves?
They have a frequency of above 20,000Hz inaudible to human ear.
What are the properties of ultrasonic waves?
THE ULTRASONIC WAVES have constant velocity in homogeneous medium. Many modes of vibration. High resolution,used for flaw detection Sonic beam and highly energetic. reflection and refraction in interface.so elastic
Which animal can hear ultrasonic waves?
whale can hear ultrasonic sound waves.
How can you trace ultrasonic waves?
What?! Trace ultrasonic waves? Are you one hundred per cent cuckoo?! Why would anyone trace ultrasonic waves these days??
Why ultrasonic waves are not electromagnetic waves?
No. They are mechanical waves, ultrasonic waves are sound waves and require a medium for propagation. The word ultrasonic denotes that they have a frequency above the audible range (above 20 KHz).
Can ultrasonic waves be polarized?
No. Only transverse waves can be polarized Ultrasonic wasves are sound waves, therefore are longitudinal.
Are ultrasonic waves called as electromagnetic wave?
No ultrasonic waves are not a form of electromagnetic wave. Ultrasonic waves are nothing more than high frequency sound waves. They can be made with a suitable speaker or transducer.
Can ultrasonic wave pass through 1Cm thick iron plate?
Yes. Ultrasonic waves can pass through metal. The only difference between "normal" sound waves and ultrasonic waves is that we cannot hear ultrasonic waves. However, they behave the same.
Which waves are used in sonography?
ultrasonic waves
What is ultrasonic cleaning?
Ultrasonic cleaning is cleaning through ultrasonic waves with some chemicals.
What is the maximum frequency of ultrasonic waves?
the minimum frequency of ultrasonic waves used in medical applications are (1-10)mhz. It may also extend to 20 MHz in foetus ultrasound.
What are ultrasonic sensors also known as?
Ultrasonic sensors are also known as transceivers but are more generally called transducers. Ultrasonic sensors work similar to radar or sonar which generate high frequency sound waves.
