    Every colour has a different wave length, but bundled it only has one, the white one. - am I right in thinking this way ? Is there a theorem for that phenomen ? - please let me know. ;-)

    Why does the refracted ray(before the screen is kept) is still white?why cant we see the VIBGYOR in mid air also?

    This is some screwed up crap. 2:00 it talks about how white light is made of 2 lights, because half work one way, and the other half work another. And solid proof that white light has 2 lights, like the sun as in one light and the moon as the second light and both above your heads. No proof what so ever to show how red, orange and yellow make white, just one end of the color spectrum.

    So what would the color pattern project with a 2 dimensional square or round slit of white light? In looking at the sunlight projecting a curious pattern through the square shaped beveled glass on my front door this morning. Top down-violet, blue, white(center of glass is flat,1/2" beveled edges, 1/4" pane)yellow,red. Left to right looking with the light, red, yellow, white, blue, violet. WHY is red or violet not the initial edge color of the symetrical square beveled glass? .......with respective colors following as the square beveled glass thickens towards the middle? The glass is symetrical BUT the refraction is not. Anyone? Thank you

    I to everyone who cant figure out how he got a beam of white light. Its clearly sunlight. its the best light for this and the beam can be created by a couple pieces of cardboard over your window. or just barley crack your curtains if you have dark enough curtains to block most of the light.

    is there any artificial source of white light that you know of that can be used to accomplish this experiment well? If so, what is it, and how would you set it up? I have not found a good way to adequately collimate light from an incandescent source. Thank you.

    I still don't understand why the triangle shape (section of the prism) separate the colors and the rectangle or square don't, we can see only a refraction? In another words, how the photon knows the glass has different shapes and decide to take different directions?

    • celio gouvea
      celio gouvea Year ago

      +Aahana Agarwal​ I know, I am talking about the section of the prism. The dispersion occurs right after the photons enter the prism, while in a square section just refract, do you understand what I am trying to explain?

      +arifa haque​ the dispersion starts while photon enters the prism so, how the photon knows the shape of the glass? I think the shape stretchs space time, there's no other possibility to explain this phenomenon.

    Amazing ! Great Video ! Thx For Sharing.
    All i could think of was creation, The Ancient Egyptians , the Pyramids.
    And eventually what we see and perceive and resonate with in this world.
    A tiny little bit that is summarized in 3 Main Colors.
    Was the World really meant to have 3 religions ?
    Why Choose the Middle one ? Is it because it is the highest ?
    I guess a Deception Really had to be put in the middle.
    Just like with the Death of Jesus.
    While in fact the 3rd one is the Right one.
    You keep looking at the light and all its aspects really forgetting all the rest.
    The Pyramid System is misunderstood and can be an Illusion according to Moses.
    That's why he took his people away.
    I think that was a Jesusy time as well and people could have swor by the stars too.
    He took them (and they considered him their savior) from that point they though wrong.
    But ended up right somehow also.
    Because he was taking them from the pyramid system to the Cube one.
    And i could go on and on about this.
    Good Luck Champ.
    If you like this kind of Stuff.
    BioGeometry would really expand your knowledge giving it a really nice boost.

    If the prism diffracts the white light into its component seven colours then why is the beam of light coming out of the prism still white in colour? And why do we see the colours/spectrum only on the screen?

    Also, you did NOT "form those colors from white light without a prism". Meaning you did not prove that is isn't the prism that is responsible for making the colored light.
    But your work here is not completely in vain.
    The lesson to be learned here, is, that the shape of your color light is being caused by your prism. Which means that the shape of a rainbow in nature must be caused by that which is causing the colored light in the first place.
    Indoors, it is not the white paper that causes the color, it is the prism. Outdoors the water droplets only take the place of the paper. Water droplets are not the proper shape to create a rainbow, like a prism does. Also, as you demonstrated, the rainbow is not seen at the prism but rather at some distance from the prism. This is one of many reasons the water droplets are not the source of the colored light, they are just the projector screen.
    The important thing is the shape of the colored light. Rainbows, in nature, are the shape they are for a reason. Just like your rainbow indoors.
    The fact that the cause of a rainbow's arc is not included in the explanation of how they are created creates a bit of an issue. Combined with the fact that your rainbow does not arc supports this.

    When you use the red filter the light just seems to be white, until it passed through the red filter. Here, it is clearly the filter that causes the white light to turn red. Similarly, we get green light with a green filter, and so on. Why then, when you pass the same white light through a dispersion prism and and we get a rainbow, do we NOT think the prism is causing the rainbow?? Review : a red filter turns white light red. A blue filter turns white light blue. Green filter turns white light green. When white light through a prism gives a rainbow? All the sudden the light we know as white must really be a rainbow?
    I have seen no proof of this. Someone needs to prove the prism is not the cause of the rainbow color light, (just like you said). Light goes through all shapes of glass and prism's and does not come out rainbow colored. Only the dispersion prism makes the rainbow...
