    The speed of electromagnetic waves are all same regardless of wavelength , they all travel at speed of light. How can u say red light travel faster than violet?

      The speed of light is constant for all wavelengths in a vacuum. However in a medium like air or glass the permittivity and permeability are different than in a vacuum so red would travel faster than violet.

    good explanation. i still dont understand why the frequency stays constant?
    p.s. for those who has the same question: the frequency stays constant because it is directly proportional to energy E=hf and since energy cannot be created or destroyed (conservation of energy law) the frequency stays constant!

      @@skmahafuzali6110 frequency is constant when the wave travels through a medium (like a glass block) think of it as a car moving through a tunnel, you cannot have more cars leaving the tunnel than entering it the same goes with waves, the frequency of each wave red and violet is different, when they are refracted their individual frequency doesn't change.

    This is false , you said frequency is constant , this is ok ,but then you said because it's constant and wavelength of red is more than WL of violet then velocity of red is more than velocity of violent , but this is not logical because you said frequency is constant for a particular light and then you compare v of red with v of violet ,this is not true because we didn't say their f are equal they are constant
    Vr/Vv=fr×WLr/fv×WLv
    fr and fv are constant but not equal so we can't say
    Vr/Vv=WLr/WLv

    All due respect. But correct me if I am wrong... aren't you simply quoting the information from textbooks? We need smart people like you to first back up, and actually do the work needed to prove the concepts you are building off of, and not just accept them as facts.
    Can you prove that it is NOT the dispersion prism (or water droplets) that is causing the rainbow effect. And do so without a prism?
    I know what the textbooks say, and so do you. Do you understand that this information has not been independently verified in our lifetimes? I mean exactly how did you personally measure the velocity of light through glass?
    Additionally, as far as red "bending" more than violet. All of the colors are touching and so close together, the difference in the amount of bend between red and violet is so small, I doubt it is discernible by humans.
    Finally, if light behaves how you say, shouldn't the sky be violet? That is at least reasonable. The fact that the sky is not violet means something about light is incorrect.
    I don't mean to be a pain in the neck. I truly think there are major issues regarding the current model and we need people like yourself to figure out the reality of the situation we find ourselves in . Cheers! : )
