Bubble of the new discovery

Newton's father carrying a hoe, greeted with a dandelion stem section is intently son blowing soap bubbles: "Children, go to the sugar pea weeding it, such a great person, but also like a child loves a bloody fool . "
"Dad, you look at the bubbles, colorful in the sun, have a variety of colors ?????? it!!"
"This is what is curious, the original is such a soap bubble."
"No, it is reasonable, indicating that the sun is not just a color."
"Bubbles have anything to do with sunlight? Who does not know that the sun just white? Do polyneuropathy was
The work and go, kids. "
"The problem is not so simple, I have to seriously look at." This had always displayed a dice "great strength" of the Newton in the event of a doubt, do not get to the bottom, is not easily let go. That year, he just graduated from Cambridge University, filled with a great plague in London, put him back to his hometown from the capital. The next day, the sky so clear and strong then, the sun remains so bright. After a night of brood, when the ???? glare of the sun to bed and wake from Newton, he felt himself to find out the secret of the white sun. So he stood up out of bed Yi Gulu, to collect some of the necessary equipment and started a new experiment.
In his collection of experimental apparatus, the number of glass up to the. Because Newton said: soap bubbles, but
The equivalent of one hollow glass balls only, since the bubble in the sunlight, can present a variety of Yen
Color, then, by the light of the glass slide, do not they should see the color it?
Newton in the window while blowing soap bubbles, while holding the glass up to the window and look carefully, but he changed the number of consecutive blocks of glass, did not see the above appear colorful colors. The soap bubbles under the sun, but still colorful. Why is this in the end? Continue to ask ourselves the Newton. Am I to infer wrong?
While Newton impatient when inadvertently given a piece of the hands of the three prism glass, when a shaking it against the light, the miracle occurred in front. Three-prism glass piece, showing a bubble similar to the landscape. Soap bubbles in the sun than the flickering ???? colors, three colors on the glass prism is more stable and hierarchical sub-section show. Number of Newton up quickly: "ah! There are seven blue-violet color of red-orange Huang Lvqing it. Well, that is, the sun contains seven colors." Newton as his new found cheering and dancing. However, he immediately thought further, since white light into seven colors can be dispersion, then, the seven colors of light that come together, do not get the same white light it?
So he rushed to a convex lens placed between the prism sheet and a white screen. Instantly, he expected results ??sf emerged, after a seven-color triangular glass scattered light and gathered up, white screen clearly shows a white band of light.
In this way, Newton's soap bubbles from the very ordinary, due to relentless reflection and exploration, continue to experiment, optical physics finally found a very important principle - the dispersion and aggregation of the original light
