Light less diffract

    1)I know that light with more wavelength run faster in the glass from an other with less.But why? If you tell me because has less diffract I will ask again,why it has less?

    Watch these public outreach lectures on QED by Feynman.


    The second one, I think, contains a section on diffraction, specifically. He also talks at length about the question of "what does it mean".
