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...

What is remote sensing? - Knowledge and techniques used to determine the properties of targets without direct contact between the measuring device and these targets What is the only energy that can be transmitted through a vacuum or a medium? - Electromagnetic radiation What is resolution? - Characteristics of the sensor/imagery that determine the type of application What are the 4 types of resolution? - Spatial, spectral, temporal, radiometric What is spatial resolution? - Defined b...

it is the bouncing back of the light into the same medium it has been travelling after striking a surface - correct answer Reflection a line perpendicular to the surface at thhe point of incidence - correct answer normal the ray that strikes the surface - correct answer incident ray the angle between the incident ray and the normal - correct answer angle of incidence The angle between the reflected ray and the normal - correct answer angle of reflection the ray that rebo...

If a light beam passes through a green sunglasses lens, why will the exciting light be green? - ️️The green rays are refracted through the lens and all other color rays are absorbed by the pigments in the lens material hen a ray of light travels from water into air ( which is rarer than water) what happens to the ray of light if the ray of light is not perpendicular to the surface? - ️️If the ray is not perpendicular to the surface it speeds up and changes direction away from the n...

reflection return of the ultrasound wave to the transducer from a smooth surface when does the greatest amount of reflection occur when the incident beam is perpendicular to structure (specular reflection) scatter deflection of ultrasound waves from small structures (red blood cells scatter sound) refraction deflection of Ultrasound waves due to media with varied acoustic impedance attenuation loss of Ultrasound signal due to absorption in tissues as it travels ...

Absorption - Answer in terms of light and lens- when a ray of light enters a lens some of the light will not completely travel through the lens Deviation (Angle of) - Answer the angle a ray of light is changed from its original path Diffuse Relection - Answer a reflection from a rough surface- the reflection does not produce a clear image Incidence (Angle of) - Answer the angle which a ray of light makes the surface of a refracting medium Reflection - Answer the return...
