    Prism
In summary, the conversation discusses three tests that involve using a prism to observe how light and colors interact with different backgrounds and objects. These tests demonstrate how different colors have opposite values and are attracted to different levels of light or darkness. The conversation also mentions how certain colors can be combined to create other colors and how energy levels and logical positions play a role in color perception. Finally, it suggests recording the distance needed to create a rainbow using a prism.

You will need: a prism, two 3 x 5 white card or paper, pencil.

Use the Sun, or any household light, even Moon reflection
____________________________________________________________________

Test One

Step One: stand in area where the background is darker than the paper, and is evenly colored. Hold paper in one hand, and the prism in the other, about 12" from each other.

Step Two: look through prism at paper, turning prism until light is "bent" and you see this on the edges of paper

|----------red-----------------|
|------------yellow------------|
| |
| white |
| |
|------------cyan--------------|
|-------------violet-----------|

if background is lighter than paper, you will see this

|-----------yellow-------------|
|-------------red--------------|
| |
| darker |
| |
|------------violet------------|
|-------------cyan-------------|

You can hold your finger or pencil between prism and paper, and the same rule will be followed - finger is darker than paper so red and violet will "touch" on finger with yellow and cyan "pointing" towards the lighter paper.

This is the Basic prism experiment. From it we can deduce that red and yellow have opposite (attractive) values, yet are in the same "family" - called Slow. In the Slow family, red is "+",and is attracted to dark. Yellow is "-", and is attractred to light. The other family is called Fast, and in the Fast family, violet is "+", and is attracted to dark, while cyan is "-", and is attracted to light.

Test Two

Take one paper, and fold it in half. Draw a dark line 1/16th" (pencil lead width) wide and 1" long in the center of one half, and 3/16" x 1" in the center of the right half. Hold prism as in previous experiment (12" away), and observe the lines you have drawn on the left side first:

You will see three lines

--------- cyan (above line)
--------- magenta (over line)
--------- yellow (below line)

(in addition to the colors on the edge of the paper)

and, on the right side you'll see:

---------cyan
---------violet
---------black
---------red
---------yellow

From this we can deduce that magenta is a "parent" of red and violet, is neutral to them, and attracted to dark (parent quality).
By changing the distance from prism to paper, we see that this distance is a ratio to the amount (width) of darkness to distance. This ratio is the same for gravity and electricity (mass/ dist.).
This is the "anti-slit" experiment. A line is "what is not" in the slit.

Test Three

On the other paper draw two lines 3/16th" x 1", one on top of the other with 3/16th" between them, on the left half. On the right, draw the same two lines except only 1/16th" apart. View through prism in the same manner as above. The left will look like the last experiment, except doubled, while on the right side, you'll see this:

---------cyan
---------violet
---------red
---------(yellow)
<-green->
---------(cyan)
---------violet
---------red
---------yellow

Now we see that green is the "product" of cyan+yellow, and is a "neutral" to them, while being the "opposite" of magenta. Green is Slow neutral, magenta is Fast neutral. They do not appear together at the same time. This re-creates the "classic" prism test with one major difference. This one happens a "moment" in time sooner than classic. Why? - because of closer distance and not "waiting" the extra time for "reflection" off of wall. The extra distance in the classic test also causes "secondary" colors to appear blurred between "primary" ones. (orange, blue, and green)

In all three tests, you can change position regarding the light and get the same results. Except at 90 degrees to light, which then lines will just look normal (black).

We know from energy levels and logical "position", that the colors of cyan, magenta, and yellow are "faster" than those of red, green, and blue. This also fits Doppler shift, red slower in the "back", and cyan faster in the "front". All color combining rules still apply, with perhaps better understanding of why there is +/- (subtractive/additive).


Happy Bending!

Classic Test

It would be very helpful to re-create the Classic Prism Test (allow light through small slit pass through prism, and onto wall) AND RECORD THE DISTANCE necessary to "make a rainbow".

FAQ: Unlock the Secrets of Light with These Prism Experiments | Step-by-Step Guide

What is a prism?

A prism is a transparent object with flat, polished surfaces that refract light. It is often made of glass or plastic and is used to separate white light into its component colors.

What are some examples of prism experiments?

Some examples of prism experiments include using a prism to create a rainbow, using a prism to demonstrate refraction, and using a prism to demonstrate how white light is made up of different colors.

How do I perform a prism experiment?

To perform a prism experiment, you will need a source of white light (such as a flashlight or lamp), a prism, and a dark room. Shine the light through the prism and observe the colors that are produced. You can also try changing the angle and position of the prism to see how it affects the colors.

What can I learn from prism experiments?

Prism experiments can teach you about the properties of light, such as refraction and the visible spectrum. They can also help you understand how white light is made up of different colors.

Are there any safety precautions I should take when performing prism experiments?

Yes, it is important to be careful when handling a prism as it is made of glass or plastic and can break easily. Also, avoid looking directly at a bright light source as it can be damaging to your eyes. It is always best to perform prism experiments under adult supervision.
