What is the general trend of the angle of refraction at a given angle of incidence, as the refractive index increases?

1. since the sines are directly proportional, with the index as the constant of variation, as the index increases, so does the angle of refraction. Take a look at Snell's Law and it should be clear.

2. see Snell's Law

increasing the refractive index would decrease the angle of refraction

3. the angles are measured relative to the normal to the interface

as the index increases, the ray is refracted more towards the normal , lessening the angle of refraction

sorry, Steve

4. Clearly I was not thinking clearly.
As usual, Scott is correct.
