Electromagnetic Spectrum -
the range of electromagnetic waves extending and carries extending from radio waves to gamma rays.

Electromagnetic Wave
A wave that is partly electric and partly magnetic and carries energy. Emitted by vibrating electric charges.
A wave that is partly electric and partly magnetic and carries energy. Emitted by vibrating electric charges.
infrared-
Electromagnetic waves of frequencies lower than the red of visible light.
Electromagnetic waves of frequencies lower than the red of visible light.
light year-
The distance light travels through a vacuum during one year.
The distance light travels through a vacuum during one year.
polarization-
The aligning of vibrations in a transverse wave, usually by filtering out waves of other direction.
The aligning of vibrations in a transverse wave, usually by filtering out waves of other direction.
ray-
A thin beam of light.
A thin beam of light.
ultraviolet
Electromagnetic waves of frequencies higher than those of violet light.
Electromagnetic waves of frequencies higher than those of violet light.
speed of light
The speed of light in vacuum, commonly denoted c, is a universal physical constant important in many areas of physics. Its value is exactly 299,792,458 meters per second, a figure that is exact because the length of the meter is defined from this constant and the international standard for time.
