Sir Isaac Newton was the first to use a glass prism to obtain the spectrum of sunlight. Newton split the colours of the spectrum of white light further by using another similar prism. But he could not get any more colours. He then placed a second identical prism in an inverted position with respect to the first prism, as shown in the following Figure.
Oh dear. So white light is composed of line spectra?
there must be a finite number of distinct colors
If green is 530 nm and yellow is 590 nm, are you telling me that there is no component of white light with a wavelength of 560 nm?
given that "green" and "yellow" are already assigned elsewhere?
The visible spectrum of the sun is largely continuous, apart from some dark absorption lines.
