|
air
|
|
what is aplitude
|
higher energy
|
|
Waves that use matter to transfer energy are what
|
mechanical waves
|
|
The matter used to transport the wave is a
|
medium
|
|
how can mechanical waves be classified
|
according to the direction of the motion of matter in relation to the direction of wave motion
|
|
what are trasverse waves
|
Mechanical waves in which matter moves up and down or back and forth at right angles compared to the direction of wave movement
|
|
what are longitudianl or compressional waves
|
Mechanical waves in which medium matter moves forward and backward in the same direction the wave travels
|
|
what are Radio waves, X-rays, microwaves, and visible light waves
|
examples of electromagnetic waves
|
|
what can travel through empty space and they all travel at the same speed
what is this called |
Electromagnetic waves
speed of light |
|
a wave in which particles of the medium move in a direction perpendicular to the direction which the wave moves
|
Transeverse Wave
|
|
a wave in which particles of the medium move in a direction parallel to the direction which the wave moves
|
Longitudinal Wave
|
|
how are waves generated
|
when a source of energy forces the matter in a medium to vibrate
|
|
what is a compression
|
waves are really close
|
|
what is a rarefaction
|
when waves are really far apart
|
|
what is a medium
|
a material that a wave travels threw
|
|
what are wves that require a medium to travel
|
mechanical waves
|
|
combinations of transvers and longitudinal wavess
|
surface waves
|
|
waves that move the meduim at right angles to the directin in which the waves are traveling
|
transverse waves
|
|
waves the move particles of the medium parallell to the direction that the waes are traeling
|
longitudinal waves
|
|
when an object or wave hits a surface throught which it cannot pass it bounces back
|
reflection
|
|
when a wave moves from on emedium into another medium at an angle it changes speed as it enters the second medium which causes in to bend
|
refraction
|
|
whenever a wave passes around the edge of a barrier or moves through a hole in the barrier the wave bends and spreds out
|
diffraction
|
|
generated by earth quakes
|
seismic waves
|
|
human range of hearing
|
ultrasound
|
|
souds with frequencys a human cant hear
|
infrasound
|
|
energy that is transferreed by electromagnetic waves is called
|
electromagnetic radation
