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...

scalar - correct answer quantity that represents only magnitude, e.g., time, temperature, or volume. It is expressed using a single number, including any units. vector - correct answer quantity that represents magnitude and direction. It is commonly used to represent displacement, velocity, acceleration, or force. Displacement (s) - correct answer the distance and direction of a body's movement (an airplane flies east 100 nm). Velocity (V) - correct answer the speed and directi...

What are grab samples and when is it used? - ️️A single sample taken at one place and time. Used when water quality and quantity are not variable What is used to measure flow in an open channel? - ️️Weirs or flumes. Flow is determined by the height of water at a particular point Why are particles that cause turbidity harmful? - ️️They can hide or entrap harmful organisms so that the disinfectant is unable to reach them. It calls increases CL demand which can be carcinogenic Wh...
