What happens when EM waves encounter a material medium?
The energy in the wave is partly transmitted, partly absorbed, and partly reflected.
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).
How defects in a metal block can be detected using ultrasound?
The ultrasound waves are allowed to pass through metal block to which are fitted detectors to detect the waves. If the metal block has a very small defect, such as an air bubble or a crack, then the ultrasound waves are reflected from such spots. The reflected ultrasonic waves indicates that metal block is defective.
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.

What is the output signal of ultrasonic thickness gauge?
An ultrasonic thickness gauge outputs ultrasonic waves which are reflected off a base surface. The resistance caused by the "coating layer" is measured by the magnitude of the returned waves. This resistance is used to determine a thickness measurement.
Describe at least three uses of ultrasonic technology in medicine?
Medical professionals can send ultrasonic waves into a specific part of the patient's body. Reflected ultrasonic waves are used to detect and monitor conditions such as pregnancy and certain types of heart disease and cancer.
Which animal can hear ultrasonic waves?
whale can hear ultrasonic sound waves.

Medical application of ultrasonic waves?
it is used in finding the internal organs such as babies.................................
Can ultrasonic waves be polarized?
No. Only transverse waves can be polarized Ultrasonic wasves are sound waves, therefore are longitudinal.

The reflected ultrasonic waves indicates that metal block is defective.
What are ultrasonic waves and also its properties?
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
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.
