Now that's an interesting thought...no question a prism splits or
filters the light into its different frequencies which is clearly proven
in the spectrum of the rainbow....low frequency, long wavelength red all
the way up to high frequency, short wavelength violet...
With the index of refraction, it appears to be more a deflection than a
filtering...if the transparent media is as clear as possible, like a
diamond, is a single frequency beaming through the diamond and coming
out the other side slightly offset from its original trajectory? of a
different frequency?

Whenever an electric charge accelerates (changes speed or direction) it
emits an electromagnetic wave.
Depending on how fast the charge accelerates or wiggles, it will give
off different forms of electro-magnetic radiation such as radio waves,
infra red, light waves, ultra violet, x-rays, or gamma rays (these are
in order from lowest to highest frequency.)
The entire range of these waves is referred to as the ELECTROMAGNETIC
SPECTRUM.
