For the same of incidence in media P,Q and R, the angle of refractive are`45^(@), 35^(@)` and `15^(@)` respectively. In which medium will the velocity of light be minimum? Give reason for your answer.

Text Solution

Verified by Experts

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)`
