'''Light''' can refer to [[electromagnetic]] [[radiation]] of any [[wavelength]], or to EM radiation of visible wavelengths <ref>Wavelengths of EM spectrum <i>usbyte.com</i> [http://www.usbyte.com/common/approximate_wavelength.htm]</ref> ; that stimulate the [[organ]]s of sight, having for normal human vision wavelengths ranging from about 3900 to 7700 [[ångstrom]]s (390 to 780 [[nm]]), violet has the shortest wavelength and red has the largest.

'''Light''' was the first creation of [[God]], before and different from His creation of matter.  It can refer to [[electromagnetic]] [[radiation]] of any [[wavelength]], or to EM radiation of visible wavelengths <ref>Wavelengths of EM spectrum <i>usbyte.com</i> [http://www.usbyte.com/common/approximate_wavelength.htm]</ref> ; that stimulate the [[organ]]s of sight, having for normal human vision wavelengths ranging from about 3900 to 7700 [[ångstrom]]s (390 to 780 [[nm]]), violet has the shortest wavelength and red has the largest.

It travels at the [[speed of light]]: about 186,300 [[mile]]s (300,000 kilometres) per second.

As with any wave, wavelength times frequency equals the speed of a light wave.

As with any wave, wavelength times frequency equals the speed of a light wave.

In the Biblical creation God created light on the first [[day]]; [[God]] said ''Let there be light,'' and there was light<ref>[[Genesis]] 1:3</ref>. We must thus deduce than light can exist without a source of its own, unless one counts God as a possible source.
