ARDMS SPI STUDY GUIDE QUESTIONS AND ANSWERS ALREADY PASSED In soft tissue, if the frequency of a wave is increased the Propagation Speed (PS) will... Remain the Same because stiffness and density affect Propagation Speed. What is the audible range? 20-20,000Hz >20,000Hz=Ultrasound Frequency is measured in Hertz (Hz) is Cycles per Second Not affected by sonographer Increase Frequency; Decrease Depth A period is the length of time it takes for one complete wavelength to pass a fixed poin...
