this is not how they are made naturally but how they are made for diagnostic uses: ultrasound waves are made by applying a current that is similar to the natural frequency of the piezoelectric quartz crystal, when this is applied to the crystal they produce ultrasonic waves!
ADDED: As a point of detail, quartz is rarely if ever used now, replaced by much more sensitive, artificial, piezoelectric ceramics.

JordanUltrasound waves are produced by generating high frequency sound waves through a process called piezoelectric effect. This involves applying an electrical current to a crystal that vibrates at a specific frequency, creating sound waves that can be used for imaging purposes in medical, industrial, and other applications.

What is the difference between ultrasound waves and microwaves?
Ultrasound waves have higher frequencies and shorter wavelengths than microwaves. Ultrasound waves are commonly used for medical imaging, while microwaves are often used for cooking and communication purposes. Ultrasound waves are typically non-ionizing, while microwaves can be both ionizing and non-ionizing depending on their frequency.
What waves have the shortest wavelenght and the highest frequency?
Gamma rays have the shortest wavelength and the highest frequency among all electromagnetic waves. They are produced by the hottest and most energetic objects in the universe, such as pulsars and black holes.
Which waves are used in sonography?
Ultrasound waves are used in sonography, also known as ultrasound imaging. These waves are high-frequency sound waves that are emitted from a transducer and used to create real-time images of internal organs and tissues in the body.
What is the difference between an ultrasound and a sonogram?
An ultrasound is the imaging technique that uses high-frequency sound waves to produce images of internal structures in the body. A sonogram is the image produced by the ultrasound machine during the scan, showing the internal structures being examined. In simpler terms, ultrasound is the process, while a sonogram is the result of that process.
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.
