Two equi- convex lenses A and B have same focal length, but radii of c – InterviewSolution

1.	Two equi- convex lenses A and B have same focal length, but radii of curvature differ such that RA=0.9 RB. If μA=1.63, then find μB.(μA→ Refractive index of lens A and μB→ Refractive index of lens B)
Answer» Two equi- convex lenses $A$ and $B$ have same focal length, but radii of curvature differ such that $R_{A} = 0.9$ $R_{B}$ . If $μ_{A} = 1.63,$ then find $μ_{B} .$ $($ $μ_{A} \to$ Refractive index of lens $A$ and $μ_{B} \to$ Refractive index of lens $B$ $)$
