For the same angle of incidence in media P, Q and R, the angles of refraction ate 45°,35° and 15° respectively. In which medium will the velocity of light be minimum ? Give reason for your answer.
For the same angle of incidence in media P, Q and & the angles of refraction is the minimum for the medium R. Hence velocity of light would be minimum in R as
c/v=sin i/sin r.
