The sun came round the corner of the house and eventually
streamed in through the window at the right-hand side of the room. [201
The sunlight was visible as a beam from Newton's view, side-on to
his apparatus, as it illuminated the dust in the air. In order of
events, the beam collided with the lens at a shallow angle and
became redirected and focused towards the first prism. It then
passed through the prism where it divided up into a spectrum, and [25]
struck the large board over a range of angles-red beams lit the
board lower down, violet beams higher up, with a complete rainbow
in between. Red light struck the board at precisely the position of
the lowest hole, and so passed through it. On reaching the second
prism, this red beam was further bent at precisely the same angle [30]
the first prism had bent it. But, against all understanding of the
time, after transiting the second prism the red beam became... a red
beam. Remarkable! The second prism had not altered the red
beam. So prisms do not alter the nature of light! Newton rethought
the mechanics of a prism. White light from the sun became a series [35]
of colours, but the colours could not be divided further. Sunlight,
therefore, is actually a mixture of all the colours in the spectrum,
Newton deduced. And of course, he was right. Simultaneously he
had also promoted the spectrum to a new level of importance-it
was a general property of white light and not an artefact of a prism. [40]
Now this continuum of merging colours, sprawling from violet to
deep red, required some sort of classification.

Spectr
Different accounts exist of why Newton gave the rainbow, or
white light spectrum, seven colours-violet, indigo, blue, green,
yellow, orange and red. One account involves his interest in musical 145]
harmonies, where there are seven distinct notes in the scale.
Newton, the story goes, proceeded to divide up the spectrum into
spectral bands with 'width' (ranges of wavelengths for each colour)
corresponding to the ratios of the small whole numbers in the scale.
Another account involves the culture of the time, in which the 150
number seven had magical or biblical significance. Either way.
Newton's seven colours are not the best choice. If we are to divide
up the spectrum into the colours we perceive, although strictly the
colours do merge to form an infinite sequence, then today we prefer
to omit indigo from Newton's categorization. Indigo is not really 1551
seen as a separate colour. This leaves the modern spectrum with the
order: violet, blue, green, yellow, orange, red. Six colours.
