<< Shining sunlight on a prism will not 'slowdown' an EM wave but
will act as a filter to separate the different frequencies of
'broadband light' into their separate spectrums. This is similar
to a spectrum analyzer, where you can see the separate frequencies
which make up a time domain EM waveform.
Hope this helps a bit!

Great information Ken. I'd like to add to it. When light slows down it has
been theorized that it is bending or traveling further due to the medium of
which it is going through. So it is actually staying at the constant, but
having more distance to travel in order to do it. That gives an illusion
that light is slowing.

I know some don't except that idea, but hay, it's just another way of looking
at things.
