Wavepacket Envelope at Boundary

  1. Nov 5, 2007 #1
    Hi, I've had trouble finding an answer to this question and was wondering if anyone could help.

    What happens to the envelope of a wavepacket of light when it crosses the interface between two media?

    I know that the field of the wavepacket will be continuous across the boundary, but does the same apply to the envelope?

    The B field is not continuous.
