    I was playing with prism, rainbow, photons, and noticed why it does not have the purple color in the rainbow ?????

    I may be wrong, but I think purple is a mix of red and blue light, and there's no such thing as a purple wavelength. You can make purple PHOT using FILT, though I can't remember exactly how, but if you look at real world physics, it shouldn't be produced by splitting white light in this manner

    Correct. It is just an illusion and the effect of violet light is a mix between colors (additive).

    but in the rainbow you made all the colors red, orange, yellow, green, cyan, blue, why not violet?

     Because violet is on the other side of the split light so there isn't any way for the colours to mix and create violet. I think that's why

     This image should also help you understand how FILT works as well! https://goo.gl/images/3s4yg2

    The ROY G BIV model is technically incorrect, like the above posts mentioned. When you split light in that way, you actually create more than one rainbow, and purple is created by blue at the end of the rainbow mixing with the red at the end of the first rainbow and the strength of the second rainbow is always weaker than the first rainbow. There is no violet.
