The following figure represents two biconvex lenses

L_1

and

L_2

having focal length

10 \mathrm{~cm}

and

15 \mathrm{~cm}

respectively. The distance between

L_1 \& L_2

is :

The following figure represents two biconvex lenses L_1 and L_2 having focal length 10 ~cm and 15 ~cm respectively. The

Options

A $10 \mathrm{~cm}$
B $35 \mathrm{~cm}$
C $25 \mathrm{~cm}$
D $15 \mathrm{~cm}$

Correct answer

C. $25 \mathrm{~cm}$

Step-by-step solution

The following figure represents two biconvex lenses L_1 and L_2 having focal length 10 ~cm and 15 ~cm respectively. The

D=f_1+f_2=25 \mathrm{~cm}

Paraxial parallel rays pass through focus and ray from focus of convex lens will become parallel
