science 2 Flashcards
wave
a long body of water curling into an arched form and breaking on the shore.
medium
the intervening substance through which impressions are conveyed to the senses or a force acts on objects at a distance.
Transverse wave
a wave that oscillates perpendicularly to the direction of the wave’s advance
Compressional wave
waves where the particle motion is in the same direction in which the wave is propagating.
sound waves
pattern of disturbance caused by the movement of energy traveling through a medium
water waves
aves propagating on the water surface
seismic waves
a mechanical wave of acoustic energy that travels through the Earth or another planetary body.
crest
The highest surface part of a wave.
trough
lowest part of a wave
rerefraction
diminution in the density of something, especially air or a gas.
wavelength
the distance from one crest to another or from one trough to another.
frequency
The frequency of a wave is the number of waves that pass a point in a certain period of time.
amplitude
the maximum extent of a vibration or oscillation, measured from the position of equilibrium.
refraction
the redirection of a wave as it passes from one medium to another.
diffraction
the deviation of waves from straight-line propagation due to an obstacle or through an aperture
interference
two coherent waves are combined by adding their intensities
standing wave
a wave that oscillates in time but whose peak amplitude profile does not move in space.
Resonance
the quality in a sound of being deep, full, and reverberating.
eardrum
the membrane of the middle ear, which vibrates in response to sound waves; the tympanic membrane.
cochlea
The cochlea is the part of the inner ear involved in hearing.
intensity
the measurable amount of a property, such as force, brightness, or a magnetic field.
audible
exceptional volume or intensity of sound; the fact or quality of being strongly audible
decibel
how to measure the intensity of sound
pitch
how high or low a sound is
ultasonic
of or involving sound waves with a frequency above the upper limit of human hearing.
Doppler effect
is the change in the frequency of a wave in relation to an observer
music
the written or printed signs representing vocal or instrumental sound.
sound quality
assessment of the accuracy, fidelity, or intelligibility of audio output
overtone
a musical tone which is a part of the harmonic series above a fundamental note, and may be heard with it.
resonator
removes high-pitched noises along with annoying hums and buzzes
acoustics
the properties or qualities of a room or building that determine how sound is transmitted in it.
echolocation
to determine the location of objects using reflected sound.
