The first page of your reference tells the story; "The word "light" is defined here as "electromagnetic radiation of any wavelength"; thus, X-rays, gamma rays, ultraviolet light, infrared light, microwaves, radio waves, and visible light are all forms of light."
"In modern physics, the photon is the elementary particle responsible for electromagnetic phenomena. It mediates electromagnetic interactions and makes up all forms of light." 73 Gary K4FMX > -----Original Message----- > From: Repeater-Builder@yahoogroups.com [mailto:Repeater- > [EMAIL PROTECTED] On Behalf Of KD5SFA > Sent: Thursday, February 22, 2007 12:04 PM > To: Repeater-Builder@yahoogroups.com > Subject: RE: [Repeater-Builder] Re: Shiny antennas (Black, Chrome and > Salmon Colors) > > yes and no. > > Here is more info that you probably wanted to know... > > http://en.wikipedia.org/wiki/Photon > > 73, > Jon > KD5SFA > > > > > > -----Original Message----- > >From: Gary Schafer <[EMAIL PROTECTED]> > >Sent: Feb 22, 2007 10:17 AM > >To: Repeater-Builder@yahoogroups.com > >Subject: RE: [Repeater-Builder] Re: Shiny antennas (Black, Chrome and > Salmon Colors) > > > >Are not radio waves and light waves both electromagnetic waves? > >Are not all electromagnetic waves made up of photons? > > > >73 > >Gary K4FMX > > > >> -----Original Message----- > >> From: Repeater-Builder@yahoogroups.com [mailto:Repeater- > >> [EMAIL PROTECTED] On Behalf Of W8MIA > >> Sent: Thursday, February 22, 2007 1:29 AM > >> To: Repeater-Builder@yahoogroups.com > >> Subject: [Repeater-Builder] Re: Shiny antennas (Black, Chrome and > Salmon > >> Colors) > >> > >> There is one SMALL problem with your Hypothesis.
