|In the particle model of electromagnetic radiation, a particle that travels only at the speed of light and whose energy is related to the frequency of the radiation in the wave model.
|The distance light travels through a vacuum in one year.
|A wave that is partly electric and partly magnetic and carries energy. Emitted by vibrating electric charges.
|The range of electromagnetic waves extending from radio waves to gamma rays.
|Electromagnetic waves of frequencies lower than the red of visible light.
|Electromagnetic waves of frequencies higher than those of violet light.
|Term applied to materials that allow light to pass through them in straight lines
|Term applied to materials that absorb light without remission, and consequently do not allow light through them.
|A thin beam of light.
|A shaded region that results when light falls on an object and thus cannot reach into the region on the far side of the object.
|The darker part of a shadow where all the light is blocked.
|A partial shadow that appears where light from part of the source is blocked and light from another part of the source is not blocked.
|The aligning of vibrations in a transverse wave, usually by filtering out waves of other directions.
