ABOUT SHAFTISM ... Page 5
The word colour is used to describe two different things, and much confusion has therefore arisen. From the
point of view of physics, the colour of a light is simply measured by its wavelength.
The number of waves a
second, in a beam of light or for our case, a shaft of light, varies according to the colour but, whatever
the colour, they are numbered by millions of million.
At high altitudes, tiny specks of ice and dust stop the short waves of Blue light and reflect them back so
that we see a Blue sky.
At sunrise the light has to pass through more air than when the sun is overhead,
thus only the yellow and the reds get through to give us the sunset.
White light can be resolved into a spectrum (q.v.) or series of wave-lengths, the longest of these producing
the effect of red upon the eye, and the shortest that of violet.
The Spectrum is continuous from end to end
but the eye divides it roughly into six distinct colors.
Here are the colours, and as I understand it, the number of waves a second for each of the colours:
RED - 400 million millions
ORANGE - 437 million millions
YELLOW - 509 million millions
GREEN - 570 million millions
BLUE - 696 million millions
VIOLET - 750 million millions
