I have the speed of a light source in plexiglass and I need to find the change in frequency from air to plexiglass and the change in wavelength.

  • physics -

    The frequency does not change. There is no waiting line. As many pulses per second travel on both sides of the boundary.
    The speed does change.
    wavelength = speed * period = speed /frequency

    Thank you very much
