Questions
A Plano convex lens fits exactly in to a Plano concave lens. Their plane surfaces are parallel to each other. If the lenses are made of different materials of refractive indices
detailed solution
Correct option is A
plano convex lens 1f1=μ1-11R and Plano concave lens 1f2=-μ2-11R1F=1f1+1f2 1F=(μ1−μ2)1R ⇒F=Rμ1−μ2Talk to our academic expert!
