Can we get a faster light?

  1. Apr 15, 2005 #1
    As refraction index [tex]n=\frac{c}{v}[/tex] suggests that all mediums other than vacuum has [tex]n>1[/tex]. I would like to know that is there any material that allows light to gain more speed rather than losing speed? If no, can it be proved? Why you are so sure of your answer?

    I think you will find some answers in this thread

    I do not think we need yaslt (yet another speed of light thread)
