100% Verified Answers UPDATED!!!
Propagation - ANSWER movement through a medium
Wave - ANSWER Can be defined as a disturbance that moves
through a medium
Wave motion - ANSWER Can be defined as a recurring
disturbance advancing through space with or without the use of
a physical medium
Transverse - ANSWER Which type of waves are water waves
known as because the motion of the water is up and down, or
at right angles to the direction in which the waves are traveling?
Longitudinal - ANSWER Type of waves which the disturbance
takes place in the direction of propagation
Medium - ANSWER The vehicle through which the wave travels
from one point to the next
,2|Page
Reference line - ANSWER The position in which a particle of
matter would have been called if it were not disturbed by wave
motion
Wavelength - ANSWER The distance in space occupied by one
cycle of a radio wave at any given instant
Meters - ANSWER Unit of measurement that wavelengths are
expressed in
Amplitude - ANSWER A wave property that gives a relative
indication of the amount of energy the wave transmits
Wave train - ANSWER A continuous series of waves that are
called having the same amplitude and wavelength
Hertz - ANSWER The number of vibrations, or cycles, of a wave
train in a unit of time is called the frequency of the wave train
and is measured in what?
,3|Page
Hertz - ANSWER Which term refers to the number of
occurrences that take place in one second?
Velocity - ANSWER Which propagation property is the rate at
which the disturbance travels through the medium, or the
velocity with which the crest of the wave moves along?
Period - ANSWER What is the time in which one complete
vibratory cycle of events occurs?
Incident - ANSWER What is a wave called that is directed
toward the surface of the mirror?
Angle of reflection - ANSWER What is the angle between the
reflected wave and the normal called?
Law of reflection - ANSWER Which law states that "The angle of
incidence is equal to the angle of reflection?
Diffraction - ANSWER What is the bending of the wave path
when the waves meet an obstruction?
, 4|Page
Doppler Effect - ANSWER What is the apparent change in
frequency or pitch when a sound source moves either toward
or away from the listener, or when the listener moves either
toward or away from the sound source
Wave motion - ANSWER How does sound travel through a
medium?
Sound - ANSWER In the study of physics, what is defined as a
range of compression-wave frequencies to which the human
ear is sensitive?
Sonics - ANSWER Which type of sounds are capable of being
heard by the human ear?
15 Hertz - ANSWER The Navy has set an arbitrary upper limit for
sonics at 10,000 hertz and a lower limit at what?
Ultrasound - ANSWER What is the standard practice used to
refer to sounds above 10,000 hertz?
