Term
|
Definition
| a repeating disturbance that transfers energy through a matter or space |
|
|
Term
|
Definition
| a wave that has a disturbance perpendicular to the direction of motion |
|
|
Term
| compressional/longitudinal waves |
|
Definition
| waves that have a disturbance parallel to the direction of motion |
|
|
Term
|
Definition
the matter or space that a wave moves through
mechanical waves need a medium
electromagnetic waves do not need a medium to travel through |
|
|
Term
|
Definition
| the distance the disturbance is away from its equilibrium (resting) position |
|
|
Term
|
Definition
the distance from crest to crest (or trough to trough) of a wave
1 complete wave cycle |
|
|
Term
|
Definition
number of cycles per second (Hz)
divide the number of cycles by the time |
|
|
Term
|
Definition
the speed with which a wave moves through a medium
determined by teh density of the medium |
|
|
Term
| what order do the mediums go in for the velocity to be greater to smaller? |
|
Definition
soild-fastest
liquids-medium
gases-slow
if the medium doesnt change all waves move with the same velocity |
|
|
Term
|
Definition
waves created by vibrating electric charges
no medium necessary
travel at the speed of light |
|
|
Term
| electromagnetic wave examples |
|
Definition
radiowaves-radio
microwaves-microwaves, cell phone signals
infrared-heat
light-visible light
UV-ultraviolet
x rays- broken bone images
gamma rays- radiation |
|
|
Term
|
Definition
| the bouncing back of a wave |
|
|
Term
|
Definition
| the bending of a wave when it passes from 1 medium to another |
|
|
Term
|
Definition
| the bending of a wave when it asses an edge or an opening |
|
|
Term
|
Definition
| the interaction or 2 or more waves |
|
|
Term
| constructive interference |
|
Definition
| when two or more waves combine to make a larger wave |
|
|
Term
|
Definition
| when two or more waves combine to make a smaller or no wave |
|
|
Term
|
Definition
| an apparent shift in frequency of a sound wave due to the motion of an o b server and/or a wave source |
|
|
Term
|
Definition
| a series of standing waves, created by vibrating an object at its natural frequencey (resonance) |
