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 sinr is as shown in the graph. From this, one can conclude that

The critical angle for the two media is given by sin \[{{i}_{c}}=\frac{1}{\sqrt{3}}\]

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

Velocity of light in the medium is 1.73 times the velocity in the II medium
