1. The high-frequency waves are known as ultrasound.
2. They are extensively used in industries and for medical purposes.
3. They can travel long distance despite the obstacles presents within the path.
4. It is also used to clean parts located in hard-to-reach places. For example- a spiral tube, electronic components, odd-shaped parts, etc.
It is done by placing objects to be clear in a cleaning solution and then passing ultrasonic waves through them.
The high frequency helps the particles of dust, grease, and dirt to detached which finally makes the object thoroughly cleaned.
5. They are also used to detect flaws and cracks in metal blocks.
Big structures like buildings, machines, scientific equipment, and bridges are made up of metallic components. Some of them while they carry small holes that are invisible to us but they can easily reduce the strength of the structure.
Hence, these waves pass through the metal blocks and detectors are used to detect the transmitted waves if there will be any small defect then the ultrasound wave will reflect back, which will indicate the presence of the flaw or defect.
6. “Echocardiography” can also be performed using this wave, as they are made to reflect from various parts of the ‘heart’ that can form the image of the heart.
7. The instrument “ultrasound scanner” which uses ultrasonic waves can also get images of internal organs of the human body such as uterus, gallbladder, kidney, etc.
It can help doctors to detect abnormalities such as stones in the gallbladder and kidney or tumors in different organs.
It can be done by passing ultrasonic waves through the tissue of the body which gets reflected back.
These waves are then converted into electrical signals that are used to generate images of the organs which are then displayed on the monitor.
By the same process, “ultrasonography” is also done to examine the foetus during pregnancy to detect defect or growth abnormalities.
8. Ultrasound waves are excessively used to break small stones formed in the kidney into fine grains which are later flushed out with urine.
