For the same value of angle incidence, the angles of refraction in three media A, B and C are 15°, 25° and 35° respectively.
For the same value of angle incidence, the angles of refraction in three media A, B and C are 15°, 25° and 35° respectively. In which medium would the velocity of light be minimum?

From Snell's law n = sini/sinr = c/v
For given i,v ∝ sinr; r is minimum in medium A, so velocity of light is minimum in medium A.
