Flashcards

Ultrasound

Ultrasonics refers to sound waves with frequencies beyond the upper limit of human hearing, typically above 20,000 Hz (20 kHz).

Applications of Ultrasound

Ultrasound is used in a variety of applications, including medical imaging, industrial inspection, and even cleaning.

Ultrasonic wave frequency

Ultrasonic waves have a higher frequency than audible sound waves, meaning they vibrate more rapidly.

Ultrasound Imaging

Due to their high frequency, ultrasonic waves can be used to create highly detailed images of internal structures, allowing doctors to diagnose medical conditions.
