For the same angle of incidence, the angles of refraction in media P, Q and R and `35^@, 25^@, 15^@ respectively. In which medium will the velocity of light be minimum?

Text Solution

Verified by Experts

`mu = c/v = (sin i )/(sin r)`
It follows that : ` v prop sin r `
Since r is minimum in medium R therefore sin r and hence velocity of light is minimum in medium R.
