The Basics of Sound: Part 2

The Basics of Sound: Part 2

This video covers fundamental ultrasound physics concepts including how ultrasound transducers convert electrical energy to acoustic energy, the nature of sound waves as mechanical longitudinal waves requiring a medium, and key acoustic variables (pressure, density, distance) that distinguish sound from other wave types. Students learn about compression and rarefaction of molecules, the distinction between acoustic parameters for continuous waves versus pulsed sound, and how sound waves differ from transverse waves.
