world depend on the rays emitted from the sun. In this case, the question of
how these rays, the ultimate energy source for the earth, come into existence
comes to mind. Surely, that these rays, which are the key to life on earth,
serve such important purposes and, at the same time, have all the necessary
characteristics for this, cannot be attributed to coincidence. The reason for
this will be better understood when the structure of light is examined.
The energy emitted by the stars moves in waves through the void of
space. Similarly, both light and heat are emitted by the sun, which is a star,
as energy in the form of waves. The movement of this energy the stars emit
can be compared to that of the waves caused by a stone thrown into a lake.
Just as the waves in the lake have different lengths, so do heat and light have
different wavelengths as they diffuse.
At this point, it would be useful to give some information about the dif-
ferent wavelengths of light in the universe. The stars and other light sources
in the universe do not emit the same kinds of light. These different rays are
classified according to their wavelengths and frequencies. These different
wavelengths are spread over vast areas. For example, the shortest wave-
length is 10 25 times smaller than the longest wavelength (10 25 is a very big
number consisting of number 1 followed by 25 zeros) 4

The wavelengths of the rays coming from space may be of very different types, ranging
from radio waves, which have the longest wavelengths, to gamma rays, which have
extremely short wavelengths.
