  • Colour – Williams’ Taper Silhouette Experiment

    Posted on November 22nd, 2009 Brian No comments


    For our second experiment we use a tapered silhouette as shown.

    If you view this silhouette through a prism you will see a spectrum as shown below.

    In the above view the Blue and Red bands are forced into occupying the same space, therefore the combined energy plus some turbulence gives us Magenta. Where you would expect Green i.e. where the Blue and Yellow bands cross, you have the extra energy of the Red light in the Magenta which is being squeezed into the same area. This forces the total energy back into White. This I refer to as a ‘compression spectrum’.

    It should be remembered that in the slit experiment the light can expand into the dark area. In the silhouette the colour bands are under pressure from the surrounding White light. Regarding the hypothesis that Yellow light is a combination of Red light and Green light, there is no evidence of any Green light. If there was a Green band between the Yellow band and the surrounding White I might have been interested in the hypothesis.

    Note: Light acts in exactly the same way as any fluid, and follows the laws of fluid dynamics.

    To demonstrate that Green and Magenta are not ‘Primary’ colours, the following simple experiments are presented. For the 1st experiment, we have a tapered slit in place of the normal parallel slit.

    A Tapered Slit.

    If you view this slit through a prism you will see a spectrum as shown below: –

    Viewing the tapered slit through a prism.

    • As the Yellow and Cyan (Bright Blue) bands overlap the result is Bright Green.
    • As the Red and Blue bands overlap the result is Purple.
    • As the Yellow and Blue bands overlap the result is a Mid Green.
    • As the Cyan and Red bands overlap the result is Mauve (Light Purple).

    These are exactly the same as the artist’s mixing rules.

    The physicist’s distorted ‘Standard’ spectrum forces them to argue that a completely different set of physics laws must apply to light.


    1. At the thin end of the slit the amount of light passing through is drastically reduced and makes it difficult to accurately determine the colours.
    2. The Cyan band is caused by the interference effect between White and ‘true’ Blue.

    You will notice that there is no Magenta involved. Magenta requires a certain amount of compression to create the additional energy and should not be confused with the Mauves and Purples.

    The Slit and Taper Slit spectra are what I  call ‘Expansion Spectra’.
