Definition
| waves in which the particles vibrate perpendicular to the direction of the wave, or the energies run perpendicular to each other |
|
|
Term
ELECTROMAGNETIC SPECTRUM
(EM) |
|
Definition
| energy made up of a combination of magnetism and electricity; it is a transverse wave because the two energies run perpendicular (at right angles) to one another |
|
|
Term
|
Definition
| where the particles stay in there is not wave (no energy making them move) |
|
|
Term
|
Definition
| the highest point of a transverse wave |
|
|
Term
|
Definition
| the lowest point of a transverse wave |
|
|
Term
|
Definition
| the distance bestween the rest position in a wave, and the crest |
|
|
Term
|
Definition
| the distance between two corresponding points on adjacent (side by side) waves |
|
|
Term
|
Definition
| how many waves go through a point in one second; measured in Hertz |
|
|
Term
|
Definition
| how fast a wave goes; equals wavelength times frequency |
|
|
Term
|
Definition
| the lowest frequency EM wave |
|
|
Term
|
Definition
| next lowest frequency wave after radio waves; used to cook food and is produced and picked up by your cell phone |
|
|
Term
|
Definition
| 3rd lowest frequency wave; used to kill bacteria and for night vision goggles |
|
|
Term
|
Definition
| the wave in the middle of the EM spectrum; this is the light we can see |
|
|
Term
|
Definition
| (abbreviated UV waves); higher frequency than visible light waves, these are used in tanning beds, and exposure over time can cause skin cancer |
|
|
Term
|
Definition
| even higher frequency than UV waves, these can help doctors diagnose broken bones, but too much exposure has been proven to cause cancer |
|
|
Term
|
Definition
| highest frequency EM wave, these can kill cancer cells, but also kill healthy cells; atomic bombs produce them |
|
|
Term
|
Definition
| materials that don't allow light to pass through so we can't see through them; most things we see are opaque, like doors, walls, and you! |
|
|
Term
|
Definition
| materials that allos SOME light to pass through, but not all of it, so we can sort of see through it, but the view is changed; wax paper is translucent |
|
|
Term
|
Definition
| materials that allow most, or all, the light to pass through, so we can see through it; window panes and water are transparent |
|
|
Term
|
Definition
| when light energy passes through matter, light passes through transparent material |
|
|
Term
|
Definition
| when light energy is taken in matter and stops there |
|
|
Term
|
Definition
| when energy bounces back after hitting matter |
|
