Practice Exam With Questions And Correct Answers| Brand New
Version! Graded A+
Depth of view increases - ANSWERS--PRF decreases
Refraction if only two conditions are satisfied - ANSWERS--oblique
incidence
different propagation speeds of two media
refraction - ANSWERS--change in direction of wave propagation when
traveling from one medium to another
transmission with a bend
small diameter - ANSWERS--high frequency crystals
higher frequency - ANSWERS--creates deeper focus
deep focus - ANSWERS---Larger diameter PZT
,2|Page
-Higher frequency
shallow focus - ANSWERS---Smaller diameter PZT
-Lower frequency
focal depth and xducer diameter - ANSWERS--transducer diameter goes
up
focal depth goes up
directly related
focal zone - ANSWERS--half located in near zone half located in far field
far zone - ANSWERS---Far field
-Fraunhofer zone
starts at focus and extends deeper
focal length - ANSWERS--focal depth
near zone length
distance from transducer to the focus
transmitted intensity - ANSWERS--intensity of the portion of the
incident beam that after striking a boundary continues forward
,3|Page
reflected intensity - ANSWERS--the intensity of the proportion of the
incident sound beam that after striking a boundary returns back
incident intensity - ANSWERS--sound waves intensity immediately
before it strikes a boundary
near zone - ANSWERS--near zone
fresnel zone
region from the xducer to the focus
oblique incidence - ANSWERS--occurs when the incident sound beam
strikes the boundary at any angle other than 90 degrees
oblique incidence synonyms - ANSWERS---Not right angle
-Non-perpendicular
normal incidence - ANSWERS--the incident sound beam strikes the
boundary at exactly 90 degrees
normal incidence synonyms - ANSWERS--perpendicular, orthogonal,
right angle, 90 degrees
oblique angles - ANSWERS--angles with a measure other than 90
degrees
, 4|Page
obtuse angle - ANSWERS--more than 90 degrees
right angle - ANSWERS--90 degree angle
acute - ANSWERS--less than 90 degrees
incidence - ANSWERS--the angle at which the wave strikes the
boundary
impedance - ANSWERS--the acoustic resistance to sound traveling in a
medium
reflection of an us wave depends on the differences in acoustic
impedances of two media at a boundary
Impedance equation - ANSWERS--impedance (rayls) = density (kg/m^3)
x propagation speed (m/s)
thick half value - ANSWERS---Low frequency sound
-Media with low attenuation rate
thin half value - ANSWERS---High frequency sound
-Media with high attenuation rate
