A convexo-concave convergent lens is made of glass of refractive index 1.5 and focal length `24 cm.` Radius of curvature for one surface is double than that of the other. Then,radii of curvature for the two surfaces are (in cm)

`6,12`

`12,24`

`3,6`

`18,36`

Text Solution

Verified by Experts

The correct Answer is:

`1/24=(1.5-1)(1/R-1/(2R))`
`R=6 cm`
`:. 2R=12 cm`
