How is the refractive index of a material related to: Velocity of light in vacuum or air and the velocity of light in a given medium?

When light is incident on a medium at angle i and refracted into a second medium at an angle r, the graph of sin r versus sin i is as shown. From this one can conclude that (i) the velocity of light in second medium is sqrt3 times the velocity of light in the first medium (ii) the velocity of light in the first medium is sqrt3 times the velocity of ligth in second medium (iii) the critical angle of the two media is given by sin i_C=1sqrt3 (iv) the critical anlge of the two media is given by sin i_C=1sqrt2
