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? - Zigya

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?

As per Snell’s law we have,

For given i, v sin r
r is minimum in medium A, so the velocity of light is minimum in medium A.
