Question

Explain the uses of ultrasound.

Answer 1

Hint: Ultrasound is the sound wave similar to the one which we can hear. The human audible range is \[20Hz\] to \[20kHz\]and ultrasound waves are the waves of frequency higher than the upper limit of the human audible range that is greater than \[20kHz\].

Complete step by step answer:
In the electromagnetic spectrum, waves are categorized into different bands based on their frequency or wavelength. According to the American national standards institute, ultrasound waves are defined as those having frequencies greater than \[20kHz\].
There are various applications of ultrasound.
Ultrasound is used to clean electronic components which are not easily accessible in a machine. The process of cleaning is, first place the parts in the cleaning solution. Second, ultrasound waves are passed through them. Due to the high frequency of ultrasound waves, dust particles fall from the surface.
Ultrasound waves are also used to detect defects or cracks in buildings, machines, etc. Here also, ultrasound waves are passed through the object to be checked and reflection of the waves is observed on the monitor.
SONAR is the most important use of ultrasound waves. It stands for sound navigation and ranging. SONAR is a device used to measure large distances, depths of oceans and to collect information about an unknown object. It has a transmitter and detector. The transmitter radiates the ultrasound waves and the detector detects the reflected waves and studies the data.

Note:
Ultrasound is also used in the medical sector and you must have sometimes heard about it.
An ultrasound scan is used to know about the internal problems in human organs. They are directed on the body part which is to be examined and an image is made which can be seen on a monitor.
