The radii of curvature of the faces of a double convex lens are

10 \mathrm{~cm}

and

15 \mathrm{~cm}

. If focal length is

12 \mathrm{~cm}

, what is the refractive index of glass?

View answer and explanation

Correct option: C

\mu=1.5

Option C (

\mu=1.5

) is correct because it is the refractive index calculated using the lens maker's formula with the given radii of curvature and focal length.
