For the same of incidence in media P,Q and R, the angle of refractive are45^(@), 35^(@) and 15^(@) respectively. In which medium will the velocity of light be minimum? Give reason for your answer.

Answer»

SOLUTION :For the same angle of incidence in media P,Q and R the angles of REFRACTION is MINIMUM for the MEDIUM R. Hence velocity of light would be minimum in R
a `c/v=(sin i)/(sin r)`
