Questions
The minimum deviation produced by a hollow prism filled with a certain liquid is found to be 30°. The light ray is also found to be refracted at angle of 30°. The refractive index of the liquid is
detailed solution
Correct option is A
For minimum angle of deviation for a prismA=2r, ∴A=60oNow μ=sin60+302sin602=sin45osin30o=12×21=2Talk to our academic expert!
