I tend to agree with Jeremy. I think if you put your detector at the
output of the prism side you will find this effect. In fact this is how
we have different rates for light to travel through in different media.
Look at your refraction demo again at:
http://wigner.byu.edu/RefractionofLight/LightRefract.html
This is how one obtains the index. I am only talking inside the media.
There will be no speed slow down outside. One of the QED's of Light.
