Application +4 | -1

The radii of curvature of a double convex lens of glass

(\mu=1.5)

are in the ratio

1: 2

. This lens renders the rays parallel coming from an illuminated filament at a distance of

6 \mathrm{~cm}

. Calculate the radii of curvature of its surfaces.

View answer and explanation

Correct option: D

-9.0 \mathrm{~cm}

Option D (

-9.0 \mathrm{~cm}

) is correct because it is the calculated radius of curvature of the second surface of the lens using the lens maker's formula.
