Multiple spectra of refracted beams of white light on a paper surface. The spectrum is a result of the different amounts of refraction of the different wavelengths of light present. 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 | |
