What are Ultra Sonics used for??

Answer 1

Sonics are actually sound waves, Ultra is to an extreme probably outside of our ability to hear it.

Ultra Sonics are used to break up stones within our bodies as well as being used as a form of x-ray, it's what is used to see babies in the womb.

Considering your in the engineering section Ultra Sonics could be used to see into the earth to find oil or wields on steel beams to see if there are any weak points.

Answer 2

in engineering applications the ultra sonics are plays a vital role . especially in mechanical engineering. the ultrasonics are used to check the metal such that whether it contains any flaws internally. if the metal contains any flaws internally, it will not use much longer time. when i was undergone my industrial training at shipyard limited, they use ultrasonic sound metal flaw detectors for metals, which were used for ship building.

Answer 3

If I were your mother and you knew that this was going on and didn't tell me I'd be upset with you. This is not something that a sibling should handle. This is a parenting issue and it sounds like your parents are allowing your sister entirely too much freedom. Please tell your parents and the young man's parents need to know this too. This behavior is completely inappropriate at that age. I get the curiosity thing but that does not excuse this behavior. What if she and this boy have sex at age 12 and she gets pregnant? Someone needs to stop this.

Answer 4

Well we use them for testing welds in structural engineering,
Its a bit like x rays to the body but on steel whereas the ultrasonics penetrate the welded area and send back the results.
If the penetrated area has a flaw, such as perosity-(air bubbles)., it shows up on the screen and the weld --fails, --pretty much like a broken bone.
Hope this helped.

Answer 5

Ultrasonics, branch of physics dealing with high-frequency sound waves, usually in the range above 20,000 hertz (Hz), that is, above the audible range. It is to be distinguished from supersonics (see Aerodynamics), which deals with phenomena arising when the velocity of a solid body exceeds the speed of sound. Modern ultrasonic generators can produce frequencies of several gigahertz (1 GHz = 1 billion Hz) by transforming alternating electric currents into mechanical oscillations. Detecting and measuring ultrasonic waves are accomplished mainly through the use of a piezoelectric receiver (See Piezoelectric Effect) or by optical means, because ultrasonic waves can be rendered visible by the diffraction of light.

The science of ultrasonics has many applications in various fields of physics, chemistry, technology, and medicine. Ultrasonic waves have long been used for detection and communication devices called sonar, of great importance in present-day navigation, and especially in submarine warfare. Applications of ultrasonics in physics include the determination of such properties of matter as compressibility, specific heat ratios, and elasticity. Ultrasonics is employed in producing emulsions, such as homogenized milk and photographic film, and for detecting flaws in industrial materials. Ultrasound in the gigahertz range can be used to produce an acoustic “microscope”, able to visualize detail down to 1 micrometre (40 millionths of an inch). Surface acoustic waves of ultrasonic frequency form an important component of electronic control devices.

In medicine, ultrasonics is used as a diagnostic tool, to destroy diseased tissue, and to repair damaged tissue. Ultrasonic waves have been employed to treat bursitis, various types of rheumatoid arthritis, gout, and muscular injuries and to destroy kidney stones. As a diagnostic tool, ultrasonic waves are often more revealing than X-rays, which do not prove as useful in detecting the subtle density differences found in certain forms of cancer; they are also widely used to produce images of the foetus during pregnancy. When ultrasonic waves are passed through a tissue the waves are reflected in varying degrees, depending on the density and elasticity of the tissue. Using an ultrasonic “scalpel”, a surgeon can make an finer incision than with a conventional surgical knife. Such techniques have been used in delicate surgery on the brain and the ear. Diathermic devices in which ultrasonic waves are used to produce heat internally as a result of tissue resistance have been used successfully in physical therapy.
