Why are ultrasound waves partly reflected by body organs?
Ultrasound waves are reflected by body organs due to differences in acoustic impedance at tissue boundaries. When ultrasound waves encounter a boundary between tissues with different densities, some of the wave energy reflects back while some continues through, resulting in echoes that are used to create an ultrasound image.
What are two applications of ultrasonic waves?
Two applications of ultrasonic waves are medical imaging, such as ultrasounds used to visualize internal organs and structures in the body, and industrial testing, like using ultrasonic waves to detect defects in materials or to clean surfaces.
What are some examples of ultrasonic sound and how is it used in various applications?
Ultrasonic sound examples include medical imaging, cleaning, and distance measurement. In medical imaging, ultrasonic waves are used to create images of internal organs. In cleaning, ultrasonic waves are used to remove dirt and grime from objects. In distance measurement, ultrasonic waves are used in sensors to determine the distance between objects.
What happens when EM waves encounter a material medium?
When electromagnetic (EM) waves encounter a material medium, they can be absorbed, transmitted, or reflected depending on the properties of the medium. The interaction between the EM waves and the medium can result in effects such as refraction, dispersion, or attenuation of the waves as they pass through the material. The behavior of EM waves in a material medium is determined by factors like the frequency of the waves, the composition of the material, and the electrical properties of the medium.
What is the standard value of velocity and wavelenght of ultrasonic waves in benzene?
The standard value of velocity of ultrasonic waves in benzene liquid is 1260 m/sec.
What happens when EM waves encounter a medium?
The energy in the wave is partly transmitted, partly absorbed, and partly reflected.

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.

A wave travelling in air falls on glass plate It is partly reflected and partly refracted The phase difference between reflected and refracted wave is?
The phase difference between the reflected and refracted waves is π radians (180 degrees). This means that the two waves are in opposite phases when they interact with the glass plate.
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.................................
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.
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
