Chapter 1: The Basics
1. Is the x-axis horizontal or vertical? The y-axis?
a. X = horizonal; Y = vertical
2. When one variable increases and the other decreases is it a direct or inverse relationship?
a. Inverse
3. Two variables that increase demonstrate what type of relationship?
a. Directly related or directly proportional
4. Define a reciprocal relationship.
a. When two numbers equal 1 when multiplied together
5. What is the reciprocal of 20?

a. Between 1 and 10
7. What is the complimentary metric unit for the following?
a. Giga
i. nano
b. Deca
i. Deci
c. Milli
i. Kilo
d. Mega
i. micro
e. Centi
i. Hecto
Ch. 2: Sound
,1. In diagnostic ultrasound, sound pulses created by a transducer travel through .
a. Media, biologic tissue
2. What do waves transfer from one location to another?
a. Energy
3. Sound must travel through a medium where molecules are alternatively and
a. Compressed – squeezed together
b. Rarefied – stretched apart
4. Are sound waves transverse or longitudinal?
a. Longitudinal
5. Define acoustic propagation properties
a. The effects of the medium upon the sound wave
6. What are the acoustic variables and what are their units ?
a. Pressure (pascals), density (kg/cm3), distance (cm, ft, miles)
7. Sound waves are also known as
a. Acoustic waves
8. What are the acoustic parameters?
a. Period, frequency, amplitude, power, intensity, wavelength, propagation speed
, 9. What are used to distinguish between sound waves and other types of waves? Acoustic
Variables or acoustic parameters?
a. Acoustic variables
10. What are used to describe the characteristics of a sound wave?
a. Acoustic Parameters
11. When particles move in a direction perpendicular to direction that the wave propagates, what
type of wave is it?
a. Transverse
12. When particles move in the same direction that the wave propagates, it is a wave.
a. Longitudinal
13. Holding a close line and shaking it up and down creates which type of wave?
a. Transverse
14. Pushing a slinky forward is an example of a wave.
a. Longitudinal
15. Describe the difference between in-phase and out-of-phase waves.
a. A wave is In-phase when their maximum values (peaks) and minimum values occur at
the same time and at the same location. Out-of-phases have peaks that occur at
different times and so do their troughs
16. Describe interference
a. When more than one sound beam travel in a medium and arrive at the same time, they
lose their individual characteristics and combine to form a single wave
17. Both in-phase and out-of-phase wave pairs undergo interference. True or False
a. True
18. What is the term for when a resulting wave is larger amplitude than either of its components?
a. Constructive interference
19. The interference of a pair of causes constructive interference
a. In-phase waves
20. When the resultant wave in smaller than one if its components
a. Destructive interference
21. The interference of a pair of waves results in the formation of a single wave of lesser
amplitude than at least one of its components
a. Out of phase waves
22. What happens when two out-of-phase waves are of equal amplitude?
a. Complete destructive interference
23. What happens when the frequencies of the waves differ?
a. Both constructive and destructive interference
24. What units are used to report the pressure of a sound beam?
a. Pascals
25. Acoustic variables allow us to determine which waves are sound and which are not. T or F
a. True
26. Acoustic parameters are used to describe the features of sound waves?
a. True
27. What is the unit for density ?
a. Kg/cm3 - concentration of mass in a volume
28. What is the definition of pressure ?
a. Concentration of force in an area
29. Definition of distance
a. Measure of particle motion
