20.
Speed of a wave
A.
A nerve that connects the inner ear with the brain and transmits sound, in the form of nerve impulses, to the brain
B.
A layer of tissue that serves as a covering, connection, or lining
C.
The highest point of a transverse wave
D.
An instrument used to detect and record seismic waves
E.
The lowest point of a transverse wave
F.
A wave that causes a medium to vibrate in a direction perpendicular to the direction in which the wave travels
G.
An opening between the middle ear and the inner ear
H.
The membrane separating the outer ear from the inner ear
I.
Region of a longitudinal wave where the particles of the medium have the highest density
J.
The spreading out of energy as it travels away from the source of the energy. The decrease in intensity as distance from an energy source increases
K.
The distance a wave travels (crest, trough, crest) in a given period of time. Speed of a wave can be calculated by multiplying wavelength by frequency
L.
The amount of electricity, light, heat, or sound energy per unit area per unit time
M.
The third in a series of three small bones in the middle ear
N.
A transfer of energy through a medium without a transfer of the medium
O.
To turn back from a hard surface
P.
When the medium and energy in a wave is turned back from a hard surface
Q.
A wave that causes a medium to vibrate in a direction parallel to the direction in which the wave travels
R.
Caused by an earthquake or vibrations inside Earth
S.
Tiny hairs that line the cochlea and help turn vibrations into nerve impulses
T.
How high or low a sound is
Type the Question that corresponds to the displayed Answer.
incorrect
21.
The material through which a mechanical wave travels
incorrect
22.
A measurement used to compare the intensity of different sounds. Each increase of 10 decibels is a sound intensity 10 times greater
incorrect
23.
The first in a series of three small bones in the middle ear
incorrect
24.
The second in a series of three small bones in the middle ear
incorrect
25.
The time required to complete one cycle of a wave
incorrect
26.
The distance between two successive crests or troughs in a transverse wave or between two successive compressions in a longitudinal wave
incorrect
27.
The number of crests or compressions in a wave that pass a point per unit time: for sound waves, measured in hertz (hz)
incorrect
28.
A tube like structure connecting the external ear to the eardrum
incorrect
29.
The height of the crest in a transverse wave; a measure of how compressed the compressions are in a longitudinal wave
incorrect
30.
A spiral tube that makes up the part of the inner ear responsible for hearing
