Colour – Williams’ Taper Silhouette Experiment
Posted on November 22nd, 2009 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.

Howdy! Do you know if they make any plugins to assist with Search Engine Optimization? I’m trying to get my blog to rank for some targeted keywords but I’m not seeing very good success. If you know of any please share. Appreciate it!

I just don’t know. I am inundated with claims (by spam) of how good these Search Engine add-ons are. However, these have only started since I’ve been hitting high positions. Since I’ve been getting higher positions than the Search Engine ‘experts’ themselves, I can’t really advise you on wether they work or not.
