| Question | Answer |
|---|---|
| diffraction | when waves spread around an obstacle |
| refraction | to change a wave's speed and direction as it travels through a medium because of the density of the medium |
| transmission | to pass through an object |
| transparent | allowing light to pass through so that object behind can be clearly seen |
| opaque | not allowing light to pass through |
| light wave | a transverse electromagnetic wave that can be transmitted, absorbed, refracted, or reflected |
| matter wave | requires a medium for matter to travel, such as water, sound, and seismic waves |
| electromagnetic wave | a wave of radiation that can travel through a medium or empty space |
| radio wave | an electromagnetic wave that does not require matter to propagate through |
| encode | to convert information into a particular form |
| digital signal | a signal in which data has been translated to a series of discrete digits like 1 and 0 |
| analog signal | a signal conveyed by continuous data often in the form of a wave |
| binary code | digital code made up of a string of only two digits 1 or 0 which is the basic input and output for computers. |
