    Introduction to Ultrasonics Ultrasonics refers to the study and application of mechanical waves with a frequency above the upper limit of human hearing, typically considered to be around 20 kHz. These waves can propagate through various media, including gases, liquids, and solids. Basics of Sound Waves Sound waves are longitudinal waves that travel through a…

    Introduction Longitudinal waves are a type of wave in which the displacement of the medium’s particles is parallel to the propagation of the wave. They are characterized by alternating regions of compressions (areas where the particles are close together) and rarefactions (areas where the particles are far apart). Wave Parameters and Properties Wave Speed The…

    Introduction The hertz (Hz) is the unit of frequency in the International System of Units (SI). It is named after the German physicist Heinrich Hertz, who made significant contributions to the study of electromagnetism. Definition One hertz is defined as one cycle per second. In mathematical terms, if a periodic event occurs once every second,…
