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 3–√ times the velocity of light in the first medium (ii) the velocity of light in the first medium is 3–√ times the velocity of ligth in second medium (iii) the critical angle of the two media is given by sini C=13–√3 (iv) the critical angle of the two media is given by sini C=12–√2
