10 , and if we counted day and night without pause, it would take us
100 million times the age of the Earth to finish. The different wave-
lengths in the universe are distributed within a spectrum of just such a
size. 70% of the different wavelengths emitted by the Sun are limited to
a very narrow spectrum between 0.3 microns and 1.5 microns. There
are three kinds of light within that band: visible light, infra-red light
25
and ultraviolet light. Despite occupying a band less than 1 in 10 , the
rays known as visible light represent 41% of all the Sun's rays.
As has been discussed, electromagnetic waves perceivable to the
human eye are responsible for only a very small part of the light spec-
trum. The other regions represent only darkness for human beings,
who are blind to wavelengths outside that band. 55

As can be seen in the diagram the wavelength range of light visible to
human beings is very narrow. Other wavelengths spell darkness to man.
