Question 155 of 295

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 :

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

Show answer and solution▾

Answer: (C) $25 \mathrm{~cm}$

$D=f_1+f_2=25 \mathrm{~cm}$
Paraxial parallel rays pass through focus and ray from focus of convex lens will become parallel
