Speed of Light HELP pleas

[hunnybunny722]

How do I use the index of refraction of a substance and then apply the definition of index of refraction to find the speed of light?

Here is a Science Buddies experiment writeup that should answer your question. You may need to investigate the links in the bibliography section and understand the definitions of the index of refraction and Snells Law to find the answer:
