Question

uses of ultra sonic sound (specially for 9th students ) ​

Answer 1

Answer:

$\huge{Heya}$

Explanation:

Most of the humans can hear up to 20 kHz, and ultrasonic waves have a frequency which is much higher than 20 kHz. Such waves are used in many fields such as navigations, medicine, imaging, cleaning, communication, mixing etc.

Ultrasound are usually high frequency waves. ultrasound are capable to travel along will-defined paths even in the occurance of obstacles.

This technique is known as 'echocardiography'.

Answer 2

Uses of Ultrasonic
Sonar -It is low-frequency ultrasonic beam used for underwater observation, communication and navigation in the study of oceanography. The sonar can penetrate deep into the ocean and be reflected back from an obstacle there; thus giving detail underwater information’s. The bottom of the ocean can be mapped properly by using an echo-sounder. The locations and proper positioning of enemy vessels can also be detected using military sonar’s.


INDUSTRY -In industry ultrasonic waves are widely employed for quality control testing. When a short pulse of ultrasound is sent into a metal, it is immediately reflected back from cracks and blow nous if any present. Along with light, sound wave is used in acoustic holography for advanced technological implications.


Medicine-For diagnosis of diseases and getting knowledge about internal organs ‘ultrasonography’ is used widely in medical science at present time. This technique is mostly employed to locate and define brain tumors, to locate the position of placenta and” fetus during pregnancy, to detect stones in gall bladder and kidneys and to identify the site and severity of arterial obstruction. The instrument used for these purposes is “ultrasonoscope.”
