Projected Light

Fig.1 shows the overlapping light beams as shown in most books on physics to try to convince the public that white light is composed of all the other colours.

Unfortunately the illustration does not show the actuality, because there are no neat uniform areas of colours as shown.  The light projectors do not project an even circle of colour as shown because the high intensity white beam always shows through the filters.

Consider the following extract: ‘It is an advantage if the projectors are controlled by rheostats, so that the relative intensities can be controlled in order to produce a good white’.  From PHYSICS – An Examination Course. By E. L. Hansen. Hulton Educational Publications Ltd.  In other words, if the physicists cannot obtain the results that they want, they are allowed to cheat. To be fair they don’t understand that it is cheating.

If you look at a Blue filter lying on a white sheet you see an even blue shade across the whole filter. If you shine a light through any filter you get results similar to those shown below.

It is obvious that a considerable amount of white light is coming through the filters. If we re-label the above drawing to allow for this white light we arrive at the following drawing.

In the above drawing we are looking at the combined colour energy levels in particular areas. We are also getting dangerously close (If you are a physicist) to the artists colour mixing principles.

In the ‘Yellow’ area the combination of colours would give a yellow ochre. In the ‘White’ area the combination would give a very light grey. The white intensity from the lamps is very much higher than the white intensity from a ‘White’ screen, and therefore a relatively small amount of white light has a far greater impact than you would expect. Referring back to the chapter on the energy value of coloured light, the white light from the lamps has a probable intensity of at least 10 times greater the yellow light from the filters.

Colour – Williams’ Taper Silhouette Experiment

.

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.

Colour – Williams’ Taper Slit Experiment

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.

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

• 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.

Notes

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’.
