““To start with you should know what a spectrum To start with you should know what a spectrum is: when white light is shone through a prism it is: when white light is shone through a prism it is separated out into all the colours of the is separated out into all the colours of the rainbow; this is the visible spectrum. So white rainbow; this is the visible spectrum. So white light is a mixture of all colours. Black is NOT a light is a mixture of all colours. Black is NOT a colour; it is what you get when all the light is colour; it is what you get when all the light is taken away.” –Purchon.comtaken away.” –Purchon.com

““These radio/light waves have a very short These radio/light waves have a very short wavelength; their wavelength is longer wavelength; their wavelength is longer than visible light. Infra-red can be detected than visible light. Infra-red can be detected by special infra-red film.” -Purchonby special infra-red film.” -Purchon
