why did you think it happened?

  refraction angles are wavelength dependent, i thought...not the fraction of c by wavelength of photon. from the wikipedia article on dispersive prisms, for example, though i asked above because i remember this from physics at Fermilab in high school. > The refractive index of many materials (such as glass) varies with the wavelength or color of the light used, a phenomenon known as dispersion. This causes light of different colors to be refracted differently and to leave the prism at different angles

    Frequency is constant, wavelength changes and so does velocity, from wikipedia refractive index > The refractive index, n, can be seen as the factor by which the speed and the wavelength of the radiation are reduced with respect to their vacuum values: the speed of light in a medium is v = c/n, and similarly the wavelength in that medium is λ = λ0/n, where λ0 is the wavelength of that light in vacuum. This implies that vacuum has a refractive index of 1, and assumes that the frequency (f = v/λ) of the wave is not affected by the refractive index.
