20 terms
Terms | Definitions |
|---|---|
 concave | a lens that is curved inward; bends light outward |
| convex lens | a lens that is curved outward; bends light inward |
| crest | the top of one wave length |
| electromagnetic spectrum | the full range of electromagnetic waves from longest to shortest (includes radio waves, microwaves, infrased waves, visible light, ltraviolet light, x-rays,, and gamma rays) |
| infrared light | invisible light felt as heat |
| laser | a concentrated beam of light, made of just one type of length |
| light | a form of energy that travels in straight lines from its source in waves (commonly called "rays") |
| light waves | are characterized by their wave lengths (Red has the longest, and violet has the shortest) |
| opaque | allowing no light to pass through and object (SHadows may be cast by opaque objects) |
| prism | refracts visible lights so that the rays are bend and seperated into the colors of the spectrum |
| reflected | light that bounces off an object or surface (such as a mirror) |
| refracted | light that is bent as its path is changed (such as when light passes through different object like a lens or water) |
| ROYGBIV | the colors or white light broken down by wavelengths in order from longest to shortest |
| translucent | allowing some light to pass through an object (the image will be disorted) |
| transmitted | light passed through and object |
| transparent | allowing all light to pass through and object |
| trough | the bottom of one wavelength |
| ultraviolet light | invisible light to humans (causes sunburns and tans) |
| visible spectrum | light that appears white because of different wavelengths traveling together (the light people can see) |
| wave length | the distance between one crest to another crest or the distance between on trough to another trough |
