|---|
| electromagnetic waves | Transverse waves of changing electric and magnetic fields |
| photon | tiny, particle-like bundles of energy |
| modulation | process of varying radio waves |
| opaque | absorbs or reflects all light, none gets through |
| transparent | allows almost all light through (clear) |
| translucent | allows some light through (blurry) |
| magnetic field | produced by electric fields, magnets and vibrating charges |
| electric field | produced by magnetic fields and exert a force on charged particles |
| scattering | causes red sunsets and sunrises |
| polarized light | light waves that vibrates in only one plane |
| diffuse reflection | reflection that allows you to see objects |
| regular reflection | reflection that allows you to see an image of an object |
| image | a copy of an object produced by reflection |
| thermogram | a color coded picture that shows temperatures |
| amplitude modulation | radio waves with frequencies that stays the same |
| frequency modulation | radio waves with amplitudes that stays the same |
| intensity | The rate at which a wave's energy flows through an area |
| photoelectric effect | when high energy light shines on a metal, it emits electrons |
| electromagnetic spectrum | radio, infrared, light, UV, Xrays, and Gamma rays |
| electromagnetic radiation | The transfer of energy through space or matter. |
