Description
A prism sitting on a sheet of paper bearing the inverted image of 2 crossed sprectral beams. The prism refracts the various background colours but does not alter them. In Isaac Newton's time, it was believed that white light was colourless, and that the prism itself produced the colour. Newton's experiments convinced him that all the colours already existed in the light in a heterogeneous fashion, and that corpuscles" (particles) of light were fanned out because particles with different colours travelled with different speeds through the prism."
