what term is used to describe the effects of an ultrasound wave
on living tissues?
A. toxic effects
B. acoustic propagation properties
C. biological effects
D. transmission properties - ANSWER-C. biological effects
which of the following is true of all waves?
a. they travel through a medium
b. all carry energy from one site to another
c. their amplitudes do not change
d. they travel in a straight line - ANSWER-b. all waves carry
energy from one site to another
Which of the following types of waves do not require a medium in
order to propagate? (More than one answer may apply)
,2|Page
a. light
b. heat
c. sound
d. television - ANSWER-a light, b heat, c television
sound cannot travel though a vacuum and requires a medium to
propagate
Which of the following describes the characteristic of a sound
wave?
a. longitudinal, bon-mechanical
b. mechanical, transverse
c. transverse, acoustic
d. mechanical, longitudinal - ANSWER-d. mechanical, longitudinal
Sound is best described as _____.
A. a series of compressions and rarefactions
B. a transverse wave
C. a wave humans can hear
,3|Page
D. an oblique displacement of acoustic energy - ANSWER-a.
series of compressions and rarefactions
What are the acoustic variables? - ANSWER-Pressure, density,
motions of particles, (Temperature)
*PDD*
What are the units of a pressure measurement of an acoustic
wave? (More than one answer may apply)
a. atmosphere (atm)
b. pascals (Pa)
c. millimeters of mercury (mmHg)
d. Pounds/sq. inch (lbs/in^2) - ANSWER-All are correct, pascals
are used most often
Sound can be characterized as:
A. energy flowing through a vacuum
B. a variable
C. cyclical oscillations in certain variables
, 4|Page
D. a principle of acoustics - ANSWER-c. Cyclical oscillations in
certain variables
What are pressures units? - ANSWER-Pa and lb/in^2
What are density units? - ANSWER-lb/in^3 and kg/m^3
what are particle of motion units? - ANSWER-miles and cm
A force is applied to a surface. If the force is tripled and the
surface area over which the force is applied is also tripled, what is
the new pressure?
A. three times larger than the original
B. one third of the original
C. six times more than the original
D. unchanged - ANSWER-d. unchanged
pressure= force/area
if both increased by 3, the pressure remains the same
