Question

# 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

- Velocity of light in the second medium is 1.73 times the velocity of light in the I medium
- Velocity of light in the I medium is 1.73 times the velocity in the II medium
- The critical angle for the two media is given by sin
- sin

## The correct answer is: Velocity of light in the I medium is 1.73 times the velocity in the II medium
