\nUltrasonic waves are sound waves with frequencies above the upper audible limit of human hearing (typically above 20 kHz). Like all sound waves, they are mechanical waves, meaning they require a material medium (solid, liquid, or gas) to propagate. They cannot travel through a vacuum.
\n<\/section>\n
\nMechanical waves transport energy through the vibration of particles in a medium. In a vacuum, there are essentially no particles to vibrate, so mechanical waves cannot propagate.
\n<\/section>\n
\nUltrasonic waves are longitudinal waves, meaning the particle displacement is parallel to the direction of wave propagation, similar to how sound travels in air. They are used in various applications, including medical imaging (ultrasound), sonar, and industrial cleaning.
