    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 Sound waves are mechanical waves that propagate through a medium (like air, water, or solids) as a result of vibrations, creating pressure variations that the human ear detects as sound. They are longitudinal waves, where the oscillations occur in the direction of wave propagation. Speed of Sound The speed of sound varies depending on…
