Therapeutic Ultrasound Quiz

A range of frequencies commonly used in physical therapy applications of ultrasound, spanning from 0.75 to 3 megahertz.

The phenomenon where certain crystals, like quartz, convert mechanical energy into electrical energy and vice versa.

The process by which electrical energy is transformed into mechanical energy, specifically vibrations, to create ultrasound waves.

Ultrasound waves have frequencies beyond the range of human hearing, making them inaudible.

The upper limit of the frequency range that humans can perceive as sound.

A material exhibiting piezoelectric characteristics, meaning it can convert mechanical energy into electrical energy and vice versa, commonly used in ultrasound devices.

The process of converting electrical energy into mechanical vibrations to produce ultrasound waves in physical therapy.

The difference between ultrasound and audible sound primarily lies in their frequency range, with ultrasound frequencies exceeding the audible range of human hearing.

Sound waves that fall within the frequency range detectable by the human ear, typically between 20 Hz and 20,000 Hz.

The conversion of mechanical energy into electrical energy and vice versa in certain crystals like quartz, a fundamental principle in ultrasound technology.
