Well here are some
of the answers and perhaps generating more questions ???
First regarding the manifestation of the Rainbow.
We need to re-examine the so called splitting of Light.
If we pass light through a prism without the introduction of the “Slit” Light passes through the prism unchanged apart from its refraction.
If we Take however only one edge of the slit (Instead of the 2 edges of the “Slit”) we find this…
A range of colour from Yellow
. And NOT Red
I can’t change this Fact.
If you get hold of a prism out of an old camera or pair of binoculars you can very easily check this out for yourself using Sun light.
the Edge only and the colour range changes from Yellow
We have only inverted the edge
changes to Blue
I can’t change this Fact.
Now the other interesting thing, it doesn’t matter which side of the prism you place either the Edge or “Slit” on, the result is still the
But the Fact remains a prism does NOT split light on its own
, if it infact splits light in the way you have been led to believe.
Try this for yourself with a prism ???
You will find though on the limits of the Light showing from the prism 2 bands of colours but this is because the prism is both presenting the effects
of the prism as well as the effects of the slit determined by the boundaries of the prism…
So what have we established ???
Well we need both
an edge (or edges) and a Wedge of Glass or some other transparent media…
So dealing with the basic Rainbow, this effect has to be manifested by the use of 3 Components…
A light source.
A Slit (two Edges) or at least one edge.
Some refracting Component which is wedge shaped.
Note the Edge or Edges, have to be in the correct orientation
with respect to the Prism or transparent wedge.
The edge or edges that produces the Rainbow is obviously curved.
If there are 2 Edges involved they would have to be in close proximity to each other One inverted
over the other.
Or a single Component comprising of a translucent edge in this case the Sun.
Do the water droplets act as the Prism as believed, or is the Water droplets rust the reflector of Light ???
But what I am saying is that the peripheral
image of the Sun provides the Edge.
That is why the Rainbow is in the form of an arc.
Note; we often see a Rainbow ring around either the moon or Sun.
Note; the “Inner” and “Outer”, see how the Red
is on the darker side, and The Yellow
is on the Lighter side.
As in the Case of the affect of an edge has on light.
Now see the “Inner” and “Outer” appearance has been inverted, yet the Red
is still next to the Darker Edge/s…
And Note how the Blue
on the Whiter Side of the Green
is produced by the merging of Yellow and Blue.
So why is the Rainbow seen with a Whiter Disc on the "Inner" of the Rainbow yet when we look at the Sun Directly the "Inner" Disc is Now Darker or
And why do we see different levels of Black/White in the multi imaged rainbow???
I have demonstrated the Edge or Edges involved in this Phenomena so what produces the Edge???
I suggest the edge is in the Source of Light i.e. the Suns Peripheral Image.
The reason why we see a Darker disc when looking at the Sun directly is because of the brighter source of light causes the pupil to go smaller
reducing the intake of light to the eye.
Depending on the fitness of the muscles within the eye which controls the iris will determine the amount of light differently in each person.
Often Prisms are used as Mirrors too !
And White Light passes through the prism where it is used a "mirror" without splitting into any spectrum unless we introduce an edge or edges.
