its speed in the solid is
c * 420/670
its frequency in the solid is the same as in air
3x10^8m/670x10^-9m = 4.478 x 10^14 Hz

The frequency of the light wave is 4.4776 x 10^8 MHZ
and the speed of light in this solid will be 1.8805 x 10^8 m/s

The speed is c times 420/670 or about
1.88X10^8 m/s
The frequency of the light remains unchanged, so it is c/670X10^(-9) or about
4.478X10^14 Hz.

420 is my favorite #,but it doesn't move at the speed of light .
