When light is incident on a medium at angle i and refracted into a second medium at an angle r, the graph of sin i vs sin r is as shown in the graph, From this, one can conclude that

A

velocity of light in the second medium is 1.73 times the velocity of light in the I medium.

B

velocity of light in the I medium is 1.73 times the velocity in the II medium.

C

The critical angle for the two media is given by `45^(@)`.

D

`sin i_( c) = (1)/(2)`
