Which Medium Has a Lower Index of Refraction: C or D?

[rhxoehwhfh]

Light travels from medium C to medium D. The angle of incidence is larger than the angle of refraction. Which medium has the lower index of refraction? Explain your logic.

We don't spoon feed here. Show your effort.

I'll spoon feed you a hint. Study Snell's law.

oh~~~~~ i got it thank you very much

I got this answer: Fast medium will have smaller index of refraction because you can't refract the light by more than 90 degrees.
